A low cost general purpose Relay-output/opto-input board for connection to a PC with free software. Uses a RS232 port.
General purpose RS232 serial port IO controller board featuring 8 relay outputs and 4 opto-isolated inputs for use in a wide variety of control and sensing applications including load switching, external switch input sensing, contact closure and external voltage sensing.Eight independent relay outputs (can be increased to 16 if you use two 3108 units and our upgrade kit Order Code 3108U). Each output is capable of switching resistive loads up to 48Vac/24Vdc @ 5 amps max and have high quality detachable screw terminal block connectors. (*NB The relays are rated to switch up to 240Vac mains voltage but the exposed screw terminal block heads would need to be placed inside a suitable enclosure to prevent exposure to hazardous voltages).Four 5-24Vdc opto-isolated digital inputs.Housed in a high quality plastic enclosure with detachable screw terminal block connectors for all IO connections.
Can be controlled using simple ASCII text based serial protocol or our free Windows software;
