Overview
The FBM241c RH914WM is a channel-isolated discrete I/O module that supports eight input and eight output channels. Moreover, it accepts multiple voltage levels, including 15–60 V DC, 120 V AC, and 240 V AC, providing versatile field compatibility. In addition, the module ensures galvanic isolation between all channels and ground, improving safety and noise immunity in industrial environments.
Functional Highlights
This module provides high reliability and configurability for critical applications. Furthermore, configurable options include input filter time, fail-safe behavior, momentary or sustained output, and redundancy support. The rugged design meets Class G3 harsh environment standards, making it suitable for industrial installations. Moreover, the module works with termination assemblies (TAs) that offer fuses, current-limiting devices, relay outputs, and solid-state outputs for flexible integration.
