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.
