The Combo Relay/Opto Board is a very useful accessory which allows much higher voltages and currents to be controlled by our IO24 range of modules.
The board consists of 4 Relay Outputs and 4 optically isolated input channels.
The relay outputs have both Normally Open (N/O) and Normally Closed (N/C) contacts rated to 250V AC or 30V DC, both at 5 Amps. The relays’ coils are powered by an external 12VDC power supply that is capable of producing approx 350mA (need about 80mA per active relay). The 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 input channels are bridged wet contacts which are electrically isolated from all other channels and the IO24 Module. Each input channel has a LED to indicate when a signal is present on the channel.
The input channels / relay output connections are by screw terminals that will accept cables 0.5 – 2mm. The connection between the IO24 Module and the Combo Board is via a 30 cm IDC connection cable provided with the board.
The board has been designed to a 72mm standard width so that it can easily be mounted in DIN rail mounting modules.
