Series AP5101 DIN-rail Amplifier Product Information

The AP5101 incorporates a DC-DC converter that ensures the output of the unit is electrically isolated from the supply. The DIN-rail housing is constructed of a high-impact thermoplastics case with recessed screw-clamp terminals for all connections and a 25-turn zero and fine gain adjustment accessible from the front panel.

A push switch and the capability to connect remotely to an internal shunt calibration resistor are also located on the front panel. Excitation, coarse gain and switches to filter the output, are internal and easily accessible by disengaging the front panel and board assembly from the housing.

The Series AP5101 amplifier accepts both uni-polar or bi-polar input signals and can produce corresponding uni-polar and bi-polar voltage outputs. Current outputs are uni-polar.
