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

Simple relay box with 5V input, used for 24V 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.
