Part Number: IC200MDD850

The IC200MDD850 is a Mixed Output Relay module from the VersaMax family, designed for versatile control in industrial automation applications. This discrete module features four isolated discrete inputs and eight relay outputs, providing flexible connectivity options. The inputs operate on a positive logic or sourcing principle, drawing current from an AC input device, with each input having individual return paths. The relay outputs are isolated from one another, capable of driving loads up to a maximum of 2A per output. Specifically designed as a Form A output, each contact remains closed as long as the host CPU is active and the corresponding output logic bit is set to 1. Powering the output loads requires an external source, while the overall functionality is supported by the backplane. Intelligent processing is managed by the CPU or Network Interface Unit (NIU) associated with the module. Each IC200MDD850 includes standard LED indicators that clearly illustrate the on/off states of both the input and output points, with the LED operation being logic-driven and independent of the load connections. Installation is straightforward, with clear instructions provided; however, it is crucial to inspect the module upon unboxing to ensure that no damage has occurred, as installing a damaged unit could compromise the overall system. The module has a backplane current consumption of 275mA at a 5V output, and the input voltage in the on state ranges from 155 to 264VAC, while the off state voltage ranges from 0 to 40VAC.
