The model EGS01 analogue amplifier with relay outputs works as a DC amplifier for strain gauge measuring bridges. Three downstream comparators, each with one adjustment potentiometer, make it possible to set three different switching thresholds, which correspond to a specific load of the connected strain gauge force transducer. Each comparator output controls a relay and a control LED.
When switched off or if the power supply is interrupted, the three relay contacts on the output terminals 3 to 8 are open. When switched-on and below the respective set switching threshold, the output relays are operating and the relay contacts are closed. Parallel to the relay coil, a control LED is switched. It lights up as long as the output contact is closed.
The amplifier is designed for installation in a control cabinet and can be mounted on a mounting rail in a DIN rail housing made of extruded profile.
