42DC Series DC/DC

0.750″ (19.05 mm) diameter, +24 VDC In, 4-20 mA Out

The 42DC Series LVDT includes integrated electronics with an AC/AC coil. It accepts 24V DC input and offers 4-20 mA current output. The stable oscillator drives the primary coil and a precision demodulator, state-of-the-art filter and V/I converter produce smooth DC current output.

The output, unaffected by power supply variations, can be useful for applications in power generation, process control and also, where long cable length is needed. Its rugged construction will resist the shocks and vibrations occurring in most industrial environments. Units are also magnetically shielded.
