Repair GE-Emerson IC610MDL105 Series One Thumbwheel Interface Module

The GE-Emerson IC610MDL105 Series One Thumbwheel Interface Module provides an interface between the Series One or Series One Plus PCs and up to four sets of user supplied thumbwheels. Each set of thumbwheels will allow the operator to control the preset on a timer or counter, and can only function with this interface module. The 24VDC power to sense the state of these thumbwheels is provided by the power supply in the CPU base unit. 

The interface module must be installed in the same base unit as the CPU and can only be located in slots 2 through 5. Only one interface module is allowed per system. The thumbwheels and their associated wiring must be supplied by the user. The thumbwheels should be standard BCD coded and diode isolated, a standard option available with most thumbwheels.
