ARP120A8R

The ARP120A8R is an Alternating Relay with DPDT contacts and cross wired. Macromatic alternating relays for three switch applications offer a number of unique advantages over standard duplex units. contactor auxiliary contacts and control relay into one compact and economical product, reducing the number of components and minimizing assembly labor. Works with three switches instead of just one or two, LEAD, LAG and STOP. Sequence on, simultaneous off (SOSO) operation, the two loads are energized sequentially, but remain on together until the STOP switch is opened. Protects against failure of the STOP and LEAD switches, if both switches fail, the two pump motors will be energized simultaneously when the LAG switch is closed.

• Compact plug-in case utilizing industry-standard 8-pin octal socket
• 2 LEDs indicate relay status
