Data Logger Considerations Each of the six relays is controlled by a data logger control port.
Power Considerations:
The A6REL-12 consumes 30 mA per active LED. The A6REL-12 may be powered by the data logger power supply (see manual for considerations with 21X) or a separate 8.4 to 24 Vdc battery.
The A6REL-12 must be powered by a Class 2 device (Campbell Scientific power supplies conform to this requirement).
