The 170ADO53050 is a Discrete Solid State I/O Base used in Modicon Momentum automation platform modular in design. The communication adapters and processor adapters are designed to work as functional modules when they are snapped onto a Modicon Momentum I/O base. This I/O base requires that some type of Modicon Momentum adapter be attached before it can be functional. I/O bases fit into compact standard housings that can be mounted on a DIN rail or on panels in a cabinet. It read information from field sensing devices and control discrete and analogue field actuating devices. Terminal blocks and bus bars are available for use with the bases so that this base can be used to support 2, 3 and 4-wire field devices. I/O field devices and the power supply to the module are connected via three 18-pin terminal blocks and an optional 1, 2 or 3-row busbar. This I/O base supports the rest of the control system.
