Overview

The IEM-422 consists of a power supply (PSD 40-15) and an LVDT/RVDT signal conditioner (LDM-1000), pre-configured to supply a 4 to 20 mA output from a 115 or 230 volt AC supply.   The IEM-422 supplies an AC sine wave excitation to the LVDT or RVDT and then demodulates and amplifies its output. A full-wave synchronous demodulator eliminates quadrature and harmonics to maximize external noise rejection. The IEM 422 is housed in a rugged NEMA 13 enclosure to protect it from dirt, dust, water and other contaminants commonly found in industrial environments. Power, input and signal output connections are made easy by using conduit ports to make the appropriate connections. LVDT hookup is completed by mating to the box-mounted, sealed M/S-style bayonet connector. The internal signal conditioner is also capable of providing several different DC output voltage signals to accommodate varying PLC and analog I/O requirements. The frequency response is internally selectable, as is the master/slave function which allows synchronization of multiple IEM-422 transmitters to prevent beat frequencies and cross talk between transducers.
