The I/O 24 Relay Output Board can be connected to I/O port of the modules to provide 8 Isolated relay contact outputs suitable for a variety of loads.
The board consists of 8 Relays with both Normally Open (N/O) and Normally Closed (N/C) contacts rated to 250V AC or DC at 5 Amps. The relays coils are powered by an external supply 12VDC power supply that is capable of producing approx 700mA (need about 80mA per relay when the relay is active) this power supply is not provided with the board. The relay coils are controlled using a ULN via the I/O ports of the module. Each of the output port channels has an LED to indicate the relay output status.
The connections for each output channel are N/O, COM and N/C connection. These connections are by screw terminals that will accept cables 0.5 – 2mm 1 . The connection between the I/O24 module and the relay output board is via a 30 cm IDC connection cable. This cable is provided with the board.
