Input/Output Controller

Input/Output Controller

The input/output (I/O) controller comprises 40 output lines. These outputs are opto-isolated and drive relays of 10 A capacity. The relay banks are configured either to power 24 V DC, 12 V DC or perform as a potential free contact switch bank. The I/O controller also comprises a stack of identical cards with eight relays each. The address of each card can be pre-defined using the dip switch setting. The controller gets commands on a RS 485 interface wherein the relay address is software selectable. The command is dually acknowledged by the controller.
