MoTron Relay Boards come with 8 (RB-8/10) or 16 (RB-16/10) 10-amp SPDT relays (Photo shows RB-16/10). Each relay's Normally-Open, Common, and Normally-Closed contacts are brought out to a pluggable euro-style discrete_wire- to-screw_terminal connector. Power and control signals are connected through the (included) 6 inch ribbon cable to the 20-position IDC input header. Each control line is pulled up to +12 VDC and relays are turned on by switching the corresponding input to ground. These Relay Boards are designed for use with MoTron's Auto-Kall AK-16, AK-32, and TC-1 Talking Controller, as well as other relay control devices.
