Operating at a nominal voltage of 230 V AC, this module provides the interfacing capacity necessary to register high-voltage digital signals from field devices such as pushbuttons, limit switches, and electrical interlocks. It captures alternating current states and processes them into a single 1 input word format for execution within the main processor rack.\u003c\/p\u003e\n\u003cp\u003eIntegrated into the system architecture via \u003cstrong\u003eUnity Pro\u003c\/strong\u003e, \u003cstrong\u003eConcept\u003c\/strong\u003e, or \u003cstrong\u003eProWORX 32\u003c\/strong\u003e programming frameworks, the module interfaces with the local controller backplane via standard bus routing protocol. The unit is specialized for high-power processing environments where separate tracking of independent AC input circuits is mandatory to prevent cross-talk and maintain signal safety. It handles discrete data conversion with an optimized response time profile and high electrical isolation thresholds between channels as well as across the bus lines.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFeatures 16 discrete input channels structured in an isolated group
