  IEM-422 Current Transmitter

Click to Download a PDF for this Product

The IEM 422 is a line powered current transmitter designed for industrial process control applications. The unit consists of a power supply and LVDT conditioner module pre-set 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 and then demodulates and amplifies the LVDT output. A full-wave synchronous demodulator minimizes quadrature output and maximizes 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 the conduit ports to make the appropriate connections. LVDT hookup is completed by mating to the sealed bayonet-type connector.
