It interfaces discrete field signals with the control system through compatible terminal board assemblies. The supplied specifications identify 24 discrete input channels and 12 Form C relay output channels, with Ethernet connectivity and front-panel status indicators for monitoring power, communication links, and attention status.\u003c\/p\u003e\n\u003ch3\u003eFunctional Overview\u003c\/h3\u003e\n\u003cp\u003eThe IS220PDIOH1A processes discrete field signals for monitoring and relay-based control. Its input channels support active-high or active-low logic, while the relay outputs provide Form C contacts for switching external circuits within the applicable voltage and current ratings.\u003c\/p\u003e\n\u003cp\u003eThe module includes a local processor and two Ethernet ports, according to the supplied hardware description. The Ethernet indicators provide a visual indication of link or communication activity, while the power and ATTN indicators help technicians identify the module's operating status.\u003c\/p\u003e\n\u003ch3\u003eI\/O Capacity and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe PDIO pack combines the functions of discrete contact input and relay output packs in one assembly. It accepts up to 24 contact inputs and controls up to 12 relay outputs. A hardware input filter of 4 ms is listed in the supplied specifications; the actual response of the complete signal path also depends on the terminal board and control-system configuration.\u003c\/p\u003e\n\u003cp\u003eThe input isolation is specified as 1500 V in the supplied product data. Input logic can be configured as active high or active low, subject to the applicable field wiring and system configuration.\u003c\/p\u003e\n\u003ch3\u003eEthernet and Terminal Board Connections\u003c\/h3\u003e\n\u003cp\u003eThe module connects to one or two I\/O Ethernet networks through dual RJ45 connectors. A three-pin power input supplies the pack, while a DC-62 connector provides the electrical interface to the associated terminal board. The terminal board determines the applicable field signal voltage capability.\u003c\/p\u003e\n\u003cp\u003eThe supplied documentation identifies two associated terminal boards:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIS200TDBSH2A - associated with simplex PDIO applications.\u003c\/li\u003e\n\u003cli\u003eIS200TDBTH2A - associated with TMR PDIO applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConfirm the installed terminal board, control-system architecture, and field wiring arrangement before selecting a replacement pack.
