The MBH88 is supplied in a DIN rail mounting case, and provides eight optically isolated inputs and eight volt free contact relay outputs with a current rating of up to 16Amp @24vdc or 250vac each. Eight isolated inputs may be used as volt free inputs (ie. direct connection to switches or sensor contacts) or as voltage inputs (5-24vdc).
The module is mains powered via an on-board isolated universal power unit. Control is by a MODBUS RTU RS485 interface with even Parity or No Parity, baud rates of 9600, 19200, 38400 or 115200, and an address range of 0 to 127.
All relays have snubber circuits across the normally open contacts and are suitable for inductive loads such as motors, solenoids etc.
