HIMA F3322 (984332202) 16‑Fold Output Module
Product Description
HIMA F3322 (part number 984332202) is a high‑density 16‑channel safety digital output module for H41q / H51q safety PLC sub‑racks. It can drive resistive loads, inductive loads and lamp loads. The maximum load per channel is 12 W with a rated channel current of 500 mA.
Equipped with safe electrical isolation, the module de‑asserts all outputs upon loss of L‑ supply, complying with fail‑safe logic.
Primarily deployed within Safety Instrumented Systems (SIS), HIMA F3322 converts internal controller logic signals into field switch signals to actuate valves, indicator lamps, relays and other field actuators in high‑risk industrial safety control loops.
It occupies 4 TE rack width and mounts directly into I/O sub‑racks. Field wiring is completed via dedicated pre‑fabricated front‑plug cable Z7136 to simplify cabinet wiring work.

Core Advantages
- High‑density channel layout: 16 outputs within 4 TE width to save cabinet installation space.
- Integrated hardware short‑circuit current‑limiting protection; single‑channel faults will not propagate across other output points.
- Fail‑safe design: outputs are cut off immediately on loss of L‑ supply to avoid unintended actuation.
- Standard pre‑fabricated plug‑in cables reduce field wiring errors and shorten commissioning cycles.
- Native compatibility with HIMA safety PLC platforms to satisfy functional‑safety project integration requirements.
Product Features
- Independent status monitoring for each output channel; module fault diagnostics can be reported to the controller.
- Galvanic safety isolation blocks field‑side interference from propagating backward to the controller backplane.
- Short‑circuit withstand capability: current‑limit engages under channel short‑circuit; operation recovers after fault removal.
- Suitable for lamp loads and inductive actuators such as solenoid valves; external free‑wheeling diodes further extend module service life.
- I/O‑bus interface, plug‑and‑play onto sub‑racks with no extra hardware conversion required.
- CE certified for industrial safety‑related control systems.
Application Fields
- SIS safety instrumented systems for petrochemical plants, ESD emergency shutdown loop output control.
- Safety interlock control for oil‑&‑gas sites, driving field solenoid valves and audible‑visual alarm beacons.
- Safety protection system output points for power‑plant boilers and steam turbines.
- Fire & Gas (F&G) systems for chemical facilities, triggering alarm equipment and shutdown actuators.
- Safety interlocks for high‑risk process equipment in pharmaceutical and metallurgical industries.
- Machine‑safety control, switch‑output points for safety shutdown loops.
Peer‑Model Comparison within HIMA Portfolio
- HIMA F3322: 16‑channel high‑density output, 4 TE rack footprint. Preferred for projects with large output point counts and limited cabinet space.
- Versus F3330 (8‑channel output module): half the channel count with identical module width. Suited for sparsely‑allocated I/O points requiring enhanced per‑module fault isolation; comparable electrical specifications to F3322.
- Versus F3333 (4‑channel output module): fewer channels; minimal fault impact per module, deployed primarily for critical safety‑actuator single‑point outputs at higher hardware cost.
- Versus relay‑output F3422: F3322 uses transistor outputs delivering faster switching response with no mechanical relay contacts; ideal for high‑frequency actuation scenarios. Relay‑type modules are intended for higher‑current‑load conditions.

Frequently Asked Questions
Q: Is HIMA F3322 part‑number 984332202 identical hardware to F3322 module?
A: 984332202 is the complete HIMA ordering part‑number for F3322; the hardware model designation itself is F3322. Always quote full part‑number 984332202 for procurement to prevent shipping‑order errors.
Q: What size solenoid valve can be directly driven by HIMA F3322 channels?
A: 500 mA maximum per channel with load power limited to 12 W. Inductive loads must be fitted with 1N4007 free‑wheeling diodes to avoid output‑circuit breakdown induced by reverse voltage.
Q: How many HIMA F3322 modules can be installed on a single I/O sub‑rack?
A: Maximum of 10 modules under full‑rated‑load operating conditions. Simultaneously switched total load must not exceed 50 % of full theoretical output current capacity; this is a mandatory system safety constraint and cannot be ignored.
Q: Can HIMA F3322 be hard‑wired directly without Z7136 pre‑fabricated cables?
A: Physical direct wiring to terminals is technically feasible, yet wiring must strictly follow manual pin‑and‑colour assignments. For field projects, Z7136 pre‑fabricated cables are strongly recommended to mitigate safety risks caused by terminal mis‑wiring.
Q: Will HIMA F3322 get permanently damaged when output is short‑circuited?
A: Hardware current‑limiting short‑circuit protection activates above 550 mA. Short‑term short‑circuit events will not destroy hardware. Persistent short‑circuit conditions require troubleshooting of external field wiring; sustained short‑circuit stress accelerates component ageing.
Q: Does HIMA F3322 support hot‑swap operation?
A: Hardware supports rack live insertion‑and‑removal. For safety‑related systems, perform maintenance swap‑outs only under plant shutdown or safety‑bypass conditions to prevent interlock triggering.
Q: Which HIMA controller families are compatible with HIMA F3322?
A: Designed for H41q and H51q safety‑PLC platforms; it is incompatible with the newer HIMax controller series. Confirm hardware platform revision during selection phase.
Q: When HIMA F3322 module LED indicates fault alarm, how to quickly differentiate hardware failure versus external‑circuit fault?
A: Disconnect Z7136 field wiring and reset module. If alarm clears, fault originates from field cables or connected loads. If alarm persists, module hardware replacement is required.

Important Notes
- Inductive‑load circuits must be fitted with 1N4007 free‑wheeling diode (part‑no. 26 810 4004). This component cannot be omitted.
- Respect I/O‑sub‑rack total‑load limits defined in manual; simultaneous switched output current shall never exceed half of theoretical total output current capacity to avoid power‑supply overload.
- Distinguish L+ and L‑ supply pins during wiring. Output cut‑off triggered by loss of L‑ supply is normal fail‑safe behaviour.
- Use LiYY 0.5 mm² cables as specified in manual; do not arbitrarily change cable cross‑section.
- 4 TE sub‑rack installation; maintain cabinet ventilation clearance to prevent accelerated component ageing under high‑temperature conditions.
- Within safety‑critical projects, perform safety‑loop functional testing after HIMA F3322 module replacement to verify output logic satisfies process‑safety requirements.
Why Choose HIMA F3322?
For HIMA H41q / H51q safety‑PLC project selections, HIMA F3322 (984332202) is the preferred I/O module for projects with high output‑point density and constrained cabinet space. Sixteen output channels fit within a compact 4 TE rack slot, reducing sub‑rack quantity and lowering overall cabinet procurement and wiring costs.
Built‑in hardware short‑circuit current‑limiting protection prevents single‑point field‑wiring faults from cascading across other channels and reduces system‑downtime risk induced by field‑circuit failures. Native fail‑safe logic de‑energises outputs upon loss of L‑ supply, complying with SIS / ESD fail‑safe design principles.
Matched Z7136 pre‑fabricated cable assemblies drastically minimise field‑wiring mistakes and shorten project commissioning lead‑time. The module supports lamp‑loads and solenoid inductive actuators; adding simple free‑wheeling diodes enables compatibility with most common field actuators for broad application versatility.
Full controller‑side fault‑diagnosis reporting enables maintenance personnel to rapidly isolate faults among channels, field wiring or module hardware itself and cuts troubleshooting duration. Compared with lower‑channel‑count output cards, HIMA F3322 delivers superior cost‑efficiency for applications requiring large quantities of discrete output points.
