The Relay I/O peripheral board has 8 relays and 8 optically isolated inputs available for addition to several JK microsystems embedded controllers.
The on-board relays have 10 ampere, normally open contacts with a recommended maximum continuous rating of 5 amperes. The opto-isolated inputs accept 3-24VAC or DC and will withstand a momentary short to 120VAC. Both the relay contacts and the opto-isolated inputs are terminated with industrial-grade screw connectors.
