COMMUNICATIONS

• A front mounted RS232 and a rear RS485 port allow easy user interface via a PC.

• ModBus ® RTU protocol is used for all ports.• The relay supports baud rates from 300 to 19,200

bps. • Up to 32 MIF II relays can be addressed on a

single communications channel. A unique address must be assigned to each relay via a setting when multiple relays are connected.
