Description technique
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 datalogger 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 datalogger control port.
A6REL-12's with serial numbers 1445 and higher are UL-approved.

Power Considerations
The A6REL-12 consumes 30 mA per active LED. The A6REL-12 may be powered by the datalogger 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).
Enclosure Considerations
The A6REL-12 requires a non-condensing environment; a Campbell Scientific enclosure is recommended. A6REL-12's with serial numbers 1445 and higher include mounting flanges with keyhole slots that attach to the backplate of an enclosure. Grommets and screws are provided.
A6REL-12s with serial numbers 1444 and lower require the 6281 bracket kit for attachment to the backplate of Campbell enclosures.

Oui. Le CR1000 est entièrement programmable pour commander ou envoyer des alarmes. La CR1000 peut effectuer des envois à distance d'un message électronique, d’un SMS ou d’un texte, envoyer un message vocale, ou en appelant un pager. La CR1000 peut également activer des alarmes physiques telles que des sirènes et des gyrophares. Dans ce type d'installation, un dispositif de relais, tel que LR4, est généralement utilisé pour envoyer un signal de commande pour le dispositif d'alarme.
