4-20 mA signal conditioner A3

for sensors

Model A3 is a Sensor Signal Conditioner (SSC) for heavy duty application. This SSC is suitable for the connection up to four sensors or transducers which consist of strain gauge Wheatstone bridge circuit of sensing function. In application, when connected to power supply (supply voltage is 12, …, 24 Vdc), this A3 SSC provides a constant excitation voltage to Wheatstone bridge circuit of the sensor, and amplifies the output signal of the sensor to standard signals (for instance, 0~5 Vdc or 4~20 mA) for further transmission to PLC in distance. The A3 SSC has a heavy-duty aluminum housing of anodized surface treatment. Thanks to both the rubber-seals between housing cover and container and the water-proof cable gland, model A3 SSC is protected to reach IP65, and can be easily fixed to panel mounting plate with two holes at two sides of the housing.
