GELBAU
Small control unit for the monitoring of sensing strips in less dangerous applications. It fulfils safety category 1 which means that it may only be used in applications in which the risk of injury is only for slight, normally reversible injuries. If there is any doubt select one of the control units on the following pages. A low current is transmitted from the unit's connectors (Z1 & Z2) through the sensing strip, and a closed circuit is formed via a resistor (8.2 kΩ). The control unit output cuts the power if anyone/anything presses the sensing strip and also following a short-circuit or open circuit.
