The DIN Mounting Rail Amplifier GM 40 amplifies the signals of SG sensors to
output signals conforming to standards. The narrow housing shape allows space-
saving mounting near the sensors in switch cabinets on standardized DIN mounting rails. A galvanically separated supply voltage range of 10...30 V DC and the analog
outputs of ±5 / ±10 V resp. optional current output allow the direct signal
processing with a PLC-Control. All control elements are reachable behind
a detachable plexiglas panel on the front side. The sensitivity adaption of the sensor takes place on-site by a DIL-switch. Preload (tara) can be adjusted. A control signal switch allows to activate the control signal in the sensor (if available). By this, the adjustment and the subsequent evaluation can be checked at any time. Interference signals and transient conditions of the measured signal can be decreased by the input filter. The fine adjustment of the amplification and the zero point as well as the filter occurs through potentiometers.
