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. 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;

Profilab Demo Example

 

The SPO-RL8 is supported by FREE windows based software. To control the module there is no need to write any code.

  • Manual control of each relay via "Toggle" switch
  • virtual LED indication of relay status
  • Timer function - each relay can be independently made to switch on or off at timed periods
  • unlimited on/off times can be programmed
  • resolution down to 1 second
  • different times for each day if required
  • time settings can be saved in a setup file
This program has been written using ProfiLab - a low cost graphical programming package designed for data acquisition and control applications. No programming experience is needed, programs are written by connecting function blocks together with wires. Professional user panels can be designed with custom controls, and the whole program can be compiled into a stand-alone executable file, with no run-time penalties.
