Repair GE-Emerson IC655MDL512 Series Five Input Module

The GE-Emerson IC655MDL512 is a 24 VAC/DC input module with 32 circuits to connect user input devices. It has an operating voltage of 10.2 to 26.4VAC/DC and an input current of 10mA at 24VAC/DC. The 32 LEDs on the front of the module indicate the on/off status of the corresponding circuit. They can also provide the module's starting I/O address when programming the unit. 

Field wiring connections to each circuit are made to the removable terminal block on the front of the module. Input circuits are divided into four groups labeled A through D, with 8 circuits in each group. Each group of eight has a single common connection, labeled C. A power supply of either 12 to 24 VAC or 12 to 24 VDC is required to sense the state of the module inputs. Each group of inputs can be powered from a separate power source or a single power source can be used to power all groups of inputs.
