Austdac has released the Alarm Latch Relay 3 (ALR3) which is certified under IECEx certificate number IECEx ExTC 19.0017X.

The ALR3 replaces the Alarm Latch Relay 2 (ALR-2) (IECEx TSA 07.0028X) which is no longer able to be manufactured by Austdac due to parts within the ALR-2 becoming obsolete.

The ALR3 parameters match the ALR-2 parameters and the ALR3 can be used as a replacement for the ALR-2, noting that the packaging is different. The following table shows the function of each pin.
