FBM07 Contact/dc Input, P/N: CM400YH

The Contact/dc Input Interface Module (an expandable main module) and its counterpart Contact/dc Expansion Input Interface Module individually function as a 16-channel contact sensor or 16-channel dc voltage monitor. Each module performs the signal conversion required to interface these digital (i.e., on/off state) electrical input signals from the field sensors to the redundant Fieldbus. The expandable main module independently connects to the Fieldbus and is capable of supporting a single
expansion module. The expansion module connects to the Fieldbus via any expandable main module and is functionally dependent on the supporting main module.
The main module is capable of executing any one of the application programs identified in the following schedule:

• When used alone or in conjunction with an expansion module that interfaces field input
signals only, the main module executes either the Digital I/O, Sequence of Events Monitor, Pulse Count Inputs or Ladder Logic program. The configurable option for each program is Input
Filter Time.

• When used in conjunction with an expansion module that interfaces field input and output signals, the main module executes either the Digital I/O or Ladder Logic program. The configurable options for each program are Input Filter Time, Fail Safe Configuration, Fail Safe Fallback and Sustained or Momentary Outputs. If the Momentary Output configuration is selected, then Pulse Output Interval is also configurable.
