Product Description：
Characterized as a Discrete Output Pack the IS220PDOAH1A model was designed with interfacing up to two I/O Ethernet networks and other discrete output terminal boards in mind. One special function of this model is that it can control up to twelve relays as well as accept feedback signals from other terminal boards. The typical relays that can be used with this model are solid-state relays and electromagnetic relays. The solid-state relays are used with the TRLYH1B, C, D, and F terminals whereas the electromagnetic relays are used with the TRLYH1E boards. The inputs that will be received on this pack with come through the double RJ45 Ethernet connectors as well as a three-pin power input.
There is a processor board embedded in the IS220PDOAH1A pack. There are multiple processors which include but are not limited to status-indicating LEDs, local power supplies for monitoring and sequencing, a high-speed processor which includes flash and RAM memory, and even more.
