The F6217 984621702 is an 8-channel analog input module by HIMA, compliant with the IEC 61508 standard and achieving a safety integrity level of SIL 3. It supports current inputs of 0/4…20 mA and voltage inputs of 0…5/10 V, with safe isolation and a 12-bit resolution. The module incorporates a redundant processor system, enabling self-tests for A/D converter linearity, channel crosstalk, etc. With a measurement update time of 50 ms, a safety time of < 450 ms, and a basic error of 0.1% at 25°C, it ensures high precision. Channel connections feature color coding, and unused inputs require termination. Redundant connections are supported, and shielded cables are needed for anti-interference, making it suitable for safety-critical industrial automation systems.

- Signal cable: LiYCY 20×0.25 mm² (shielded), length 750 mm, cross-sectional area 1 mm².
- Power and shield cable: Flat pin (6.3×0.8 mm), grounding cable length 120 mm, cross-sectional area 2.5 mm².
- Equipped with a redundant safety-related processor system (μC1, μC2, μC3), enabling direct self-tests on the module.
- Block diagram shows components such as Analog Ground (GND-Analog), Analog Voltage (V-Analog), and Multiplexer (MUX).
- A/D converter tests: Linearity and overflow detection.
- Channel interference test: Crosstalk detection among 8 channels.
- Input filter function test: Validation of filter effectiveness.
- Bus communication test: Detection of I/O bus communication functionality.
- Microcontroller and memory test: Self-check of microcontroller and memory integrity.
- Fault indication: Channel error bits are set upon error detection, requiring evaluation in the user program.
- Range: 0/4…20 mA, 12-bit resolution (22 mA corresponds to 4095).
- Shunt parameters: 250 Ω, used to convert current to voltage for measurement.
- Current/voltage redundancy: Connect dual modules (e.g., module1 and module2) via Z7127/6217 cable plugs, suitable for safety systems.
- Voltage divider redundancy: Use 1.96 kΩ resistors (HIMA part number 000710192), considering the internal resistance of the transmitter power supply.
- Transmitter power supply: Provided via Z7128 cable plugs, applicable only for two-wire connections and not compatible with zener diode barriers.
- Unused 0…5 V voltage inputs must be terminated with jumpers.
- Unused current inputs are terminated with shunts, and unused 0…10 V voltage inputs are terminated with voltage dividers in the cable connector.
- Shielded cables are required for field input circuits, and twisted pair cables are recommended. If the environment from the transmitter to the module is interference-free and the distance is short (e.g., inside a cabinet), shielded or twisted cables can be omitted.
- Each channel corresponds to an analog input value and a fault bit, requiring safety-related responses (e.g., triggering safety actions upon faults) to be programmed in ELOP II.
- Physically separate power cables from input circuits.
- Ensure proper earthing and adopt heat dissipation measures outside the module (e.g., fans in the cabinet).
- Record operation and maintenance events in a logbook; replace the module directly in case of faults without requiring maintenance.
- Low-frequency interference (10 Hz): Interference from pressure measurements of nearby piston pumps may trigger channel error bits.
- Solutions: Use built-in digital filters in sensors or H 7017 low-pass filters (consider safety time calculation).
- Z7128 cable plug: With transmitter power supply, suitable for two-wire connections, providing power supply and signal transmission.
- Isolator application: When using transmitters with internal zener diodes (e.g., Saab/Rosemount 3300 GWR), use HIMA H 6200 analog isolators to eliminate interference.
