FOXBORO FBM216 Channel Isolation 8 P0917TN Analog Input Module

Description

A Fieldbus Communication Module or a Control Processor interfaces the redundant 2 Mbps module Fieldbus used by the FBMs. The Compact FBM216b accepts communication from either path (A or B) of the redundant 2 Mbps fieldbus. If one path is unsuccessful or is switched off at the system level, the module continues communication over the active path.

The use of an external power supply common to two or more loops requires a Cable Balun module to maintain communication signal line balance.

A small PLC flexibly controls a complex system, and all it can see is the staggered input and output relay terminals, corresponding indicator lights, and PLC numbers, just like an integrated circuit with dozens of legs. If anyone does not look at the schematic diagram to repair faulty equipment, they will be helpless and the speed of finding faults will be particularly slow. In view of this situation, we will draw a table based on the electrical schematic diagram and paste it on the control console or control cabinet of the equipment, indicating the corresponding electrical symbols and Chinese names of each PLC input and output terminal, which are similar to the functional descriptions of each pin in the integrated circuit. With this input and output table, electricians who understand the operation process or are familiar with the ladder diagram of this equipment can carry out maintenance.

But for electricians who are not familiar with the operation process and cannot read ladder diagrams, they need to draw another table: PLC input and output logic function table. This table actually illustrates the logical correspondence between the input circuit (triggering element, associated element) and the output circuit (executing element) in most operational processes. Practice has proven that if you can proficiently use the input output correspondence table and input output logic function table to troubleshoot electrical faults, without drawings, you can also easily and freely.
