A6REL-12 6-Channel Relay Driver w/ Manual Override
A6REL-12 6-Channel Relay Driver w/ Manual Override

You can control up to 12 external ac or dc devices using the six internal relays of the A6REL-12. Each relay set can be controlled manually or by a data logger.

The A6REL-12's internal relays are dual single-pole double-throw. Each of the six relays has a three position toggle switch; "on" and "off" for manual override, and "auto" for data logger control. In the on position, the common and normally open contacts are shorted. In the auto position, the state of a relay is controlled by a data logger control port.

A6REL-12's with serial numbers 1445 and higher are UL-approved.
