The FOXBORO FBM217 RH914TR discrete input module, a key component of the Compact 200 Series I/O subsystem, efficiently connects field sensor signals to the control processor with its 32-channel design. It is compatible with various termination assemblies, covering inputs such as 15-60VDC, 120VAC/125VDC, and 240VAC. It supports single-module or redundant deployment, and can switch seamlessly during redundancy to ensure stability. The ABS shell is suitable for Class G3 harsh environments, with LEDs displaying status in real-time. It is easy to install and replace, providing reliable signal conversion and processing capabilities for industrial control.

Overview of FOXBORO FBM217 RH914TR
Core Functions: It provides 32 discrete input channels, each of which accepts 2-wire input from a DC voltage source. It supports discrete inputs of below 60VAC, 120VAC/125VDC or 240VAC through related terminal assemblies (TAs), realizing the interface conversion between the on-site sensor electrical signals and FCP or ZCP.
Supported Input Types: Voltage monitoring or contact sensing of 30VDC, 125VDC, 120VAC or 240VAC.
Redundant Configuration: It can be used as a redundant pair, which needs to be installed adjacently (starting with an odd number). It is connected to the same terminal assembly through a redundant adapter (RH101AZ), and the on-site input current is doubled; the redundant digital input block in the control software verifies the input and selects high-quality signal processing. Replacing the module does not affect the on-site input signal of the normal module.
Main Features of FOXBORO FBM217 RH914TR
Channels and Voltage: 32 discrete input channels, supporting 15-60VDC, 120VAC/125VDC, 240VAC voltage signals.
Environmental Adaptability: With a compact and robust design and an ABS shell, it is suitable for the G3 level (severe) environment specified in the ISA S71.04 standard.
Function Support: It can execute discrete input, ladder logic, pulse counting and sequence of events (SOE) programs, and supports configurable options for input filtering time and fail-safe configuration.
Terminal Assemblies (TAs): They include functions such as high-voltage attenuation, optical isolation, and external power connection, providing various isolation modes (group isolation, channel isolation, paired isolation, etc.).
Visual Indication: There are red and green LEDs on the front to indicate the module status, and 32 blue LEDs to indicate the status of each input channel.
Installation and Replacement: It is installed on the Compact 200 series backplane and fixed with two screws. The module can be replaced without disassembling the on-site wiring, power supply and communication cables.
