A6REL-12 Relay Driver

1. Function

The A6REL-12 (Figure 1) drives six dual single pole double throw internal

relays for control of up to 12 external AC or DC devices. Each of the six

relays has a three position toggle switch; "on" and "off" for manual override,

and "auto" for datalogger control. In the on position, the common and

normally open contacts are shorted (Figures 2 and 3). In the auto position, the

state of a relay is controlled by a datalogger control port.

Please note that the A6REL-12 is not compatible with our CR200-series

dataloggers.
