FBM12 CONTACT/DC INPUT EXPANDER, P/N: P0400YN

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 functional
