Functioning as a direct hardware bridge between external panel controls and the PLC processor, this input module enables plant operators to adjust numerical values on the factory floor without needing a programming terminal. It processes binary-coded decimal (BCD) inputs from up to four sets of diode-isolated thumbwheel switches, allowing real-time parameter tuning in legacy automation environments.\u003c\/p\u003e\n\u003cp\u003eEngineered to interface natively with the controller's internal architecture, the \u003cstrong\u003eGE IC610MDL105\u003c\/strong\u003e specifically governs access to timer and counter presets located in references \u003cstrong\u003e674 through 677\u003c\/strong\u003e. The CPU requires this module to be physically present to execute preset modifications for these specific register addresses. Upon physical installation, the module automatically assigns eight discrete coil references to its assigned slot, maintaining structured signal mapping within the PLC I\/O map.\u003c\/p\u003e\n\u003cp\u003eTo achieve fast data handling without overloading system CPU processing, the \u003cstrong\u003eIC610MDL105\u003c\/strong\u003e executes a progressive scanning scheme that reads one thumbwheel value per PLC scan cycle. The module draws its required sensing power directly from the main CPU base unit power supply, eliminating the need for an external auxiliary power source for input logic detection. Installed strictly in slots 2 through 5 of the main CPU base, it provides a stable input solution for legacy operator control stations.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInterfaces up to four external sets of user-supplied, BCD-coded, diode-isolated thumbwheel switch assemblies\u003c\/li\u003e\n\u003cli\u003eProvides hardware execution for modifying timer and counter preset values in references 674 to 677\u003c\/li\u003e\n\u003cli\u003eAssigns eight internal discrete coil references per designated slot within the PLC I\/O memory map\u003c\/li\u003e\n\u003cli\u003eExecutes a single-thumbwheel-per-scan cycle acquisition process for data responsiveness\u003c\/li\u003e\n\u003cli\u003eOperates on internal power drawn directly from the CPU base unit supply rail\u003c\/li\u003e\n\u003cli\u003eUtilizes a standard 20-terminal wiring interface for wiring harness connectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLegacy GE Series One and Series One Plus PLC maintenance, retrofit, and system repair\u003c\/li\u003e\n\u003cli\u003eMachine tooling and industrial packaging lines requiring manual operator setting of batch counts\u003c\/li\u003e\n\u003cli\u003eLocal operator control panels needing physical BCD manual data entry for timer adjustments\u003c\/li\u003e\n\u003cli\u003eIndustrial process systems using hardware thumbwheel presets for batch or cycle control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog Number \/ SKU\u003c\/td\u003e\n\u003ctd\u003eIC610MDL105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eThumbwheel Interface Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Controller Series\u003c\/td\u003e\n\u003ctd\u003eGE Series One, Series One Plus PLCs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch4\u003eElectrical \u0026amp;
