Built as a high-voltage H6A variant, it processes 24 group-isolated 125 VDC contact inputs and drives 12 Form-C relay outputs while interfacing with PDIO I\/O packs.\u003c\/p\u003e\n\u003ch3\u003eSignal Processing and I\/O Architecture\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eIS400TDBTH6AEF\u003c\/strong\u003e manages 24 group-isolated digital input channels rated for a nominal wetting voltage of 125 VDC, operating across an input range of 100 VDC to 145 VDC. Each input channel integrates a 4 ms hardware filter to suppress electrical noise and contact bounce from field switches.\u003c\/p\u003e\n\u003cp\u003eFor output control, the module provides 12 Form-C (SPDT) relay channels capable of directly switching solenoids, contactors, or indicator lamps. Built-in channel group isolation alongside over-voltage and over-current protection prevents field ground loops from propagating into the control logic.\u003c\/p\u003e\n\u003ch3\u003eSystem Integration and Installation\u003c\/h3\u003e\n\u003cp\u003eThe terminal board connects to PDIO discrete I\/O packs via D-sub connectors, communicating with the main Mark VIe controller over IONet. While designated as a discrete simplex board, it supports Simplex, Dual, and Triple Modular Redundant (TMR) configurations depending on the quantity of mated I\/O packs.\u003c\/p\u003e\n\u003cp\u003eField wiring attaches to pluggable screw terminal blocks for straightforward maintenance and loop isolation.
