Product overview

Bus recognizer is an interface between PLC and field device. Upon receiving the address and data, this circuit board decodes the address and controls the concerned machine (for that address) via 4 On/OFF relays on the board. These relays will be ON/OFF depending on the data sent by the PLC/PC. This board supports RS485 communication and hence, twisted pair of wire is to be connected between the control of that machine. It's a 4-Channel relay module controller via RS485. Multiple boards can be cascaded on RS485 Bus
