The AP5102 series is a DIN-rail mounted signal conditioner for use with LVDTs (linear variable differential transformer) requiring AC excitation and synchronous demodulation. The AP5102 produces outputs of 0-10 Vdc, ±10 Vdc, or 4-20 mA. One of the key features of this DIN-rail amplifier is that it incorporates a DC-DC converter which ensures the output of the unit is isolated from the supply.

DIN-Rail Series AP5102 Product Information

The DIN mount housing is constructed of high-impact thermoplastic and has recessed screw-clamp terminals for all connections. Zero and span adjustments are made directly from the front panel with 25-turn trim pots. All other controls are internal including coarse gain and zero, zero input switch, jumper links for master/slave setting, and excitation frequency setting.

All internal settings are easily accessible by disengaging the front panel and board assembly from the housing. The AP5102 is compatible with the complete range of Stellar Technology AC/AC LVDT transducers.
