Foxboro FBM217 Discrete Input Interface Module

The FBM217 Discrete Input Interface Module is a device used for interfacing discrete input signals in industrial automation applications. Here are the key features and specifications of the FBM217:

Features

1. Discrete Inputs: Provides 32 discrete input channels.
2. Voltage Range: Supports discrete input signals at voltages of:
   • 15 to 60 V dc
   • 120 V ac/125 V dc
   • 240 V ac
3. Redundancy: Can be used as a single module or in a redundant pair (two FBM217s) to enhance reliability.
4. Rugged Design: Designed for use in harsh Class G3 environments.
5. Program Execution: Executes programs for Discrete Input, Ladder Logic, Pulse Count, and Sequence of Events, with configurable options for Input Filter Time and Fail-Safe Configuration.
6. Termination Assemblies (TAs): Various TAs available, providing high voltage attenuation and optical isolation for inputs, as well as external power connection for device excitation.
