Foxboro FBM207 Voltage Monitor/Contact Sense Input Modules

FBM207/b/c Voltage Monitor/Contact Sense Input Modules

Description

Discrete inputs can be sensed across all the usual voltage levels found in industrial facilities. The FBM207/b/c uses one of the several termination assemblies (TAs) to match to the externally powered voltage level. In cases where the inputs are integral to the plant’s control scheme, the FBM207/b/c may be installed as a redundant pair with standard control blocks used to manage the redundancy.

The FBM207/b/c Voltage Monitor/Contact Sense Input Module functions as a 16-channel DC voltage monitor or 16-channel contact sensor. Each channel accepts a 2-wire input from a DC voltage source (FBM207) or pair of contacts or solid state switches (FBM207b/ FBM207c).

Associated (TAs) support discrete input signals at voltages of 60 VDC, 120 VAC/125 VDC, or 240 VAC. For voltages higher than 60 VDC, the TAs have additional signal conditioning hardware that provides voltage attenuation and optical isolation.

Features

• FBM207 supports 16 discrete input signals at voltages of:

    15 to 60 VDC - voltage monitoring

    120 VAC/125 VDC - voltage monitoring or switch inputs

    240 VAC - voltage monitoring or switch inputs

• Each input is galvanically isolated, and group isolated with external excitation

• Single or redundant modules

• Rugged design suitable for enclosures in Class G3 (harsh) environments

• Executes programs for Discrete Input, Ladder Logic, Pulse Count, and Sequence of Events with configurable Input Filter Time option

• Termination Assemblies (TAs) for locally or remotely connecting field wiring to FBM207/b/c

• TAs for per channel internally loop powered devices

• Various TAs have additional signal conditioning hardware that provides voltage attenuation and optical isolation
