I built this module for Sensonor ASA back in 2008, I have no idea if it is alive today.
Relay box for strobe lamp

Information

This relay box is used for a temperature alarm at Sensonor. The trigger signal is sent from a AKCP SensorProbe2, which is a email based warning system for e.g. temperature and humidity. The strobe is placed in the production area.

Connector RJ-45

AKCP SensorProbe2 connection:

The Data output needs to be amplified using a NPN transistor. The relay is connected between the +5V and transistor output.
