IEM-422 Line Powered Industrial LVDT/RVDT Current Transmitter SPECIFICATIONS 115/230VAC line powered NEMA-13 rated enclosure 4 to 20mA output Zero, span and phase adjustable 2.5, 5 and 10kHz excitation frequencies Low noise, 3-pole Butterworth filter Master/slave capability Compatible with 4, 5 & 6 wire LVDTs/RVDTs Power and loop status LEDs The IEM-422 is a line-powered current transmitter, designed for industrial process control applications. 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 FEATURES demodulates and amplifies its output. A full-wave synchronous Rugged NEMA-13 rated enclosure demodulator eliminates quadrature and harmonics to maximize external noise rejection. Conduit ports for easy connection Pre-configured 4-20mA output The IEM 422 is housed in a rugged NEMA 13 enclosure to protect signal it from dirt, dust, water and other contaminants commonly found Bolt holes for easy mounting in industrial environments. Power, input and signal output Multiple LVDT master/slave connections are made easy by using conduit ports to make the capability 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 APPLICATIONS different DC output voltage signals to accommodate varying PLC and analog I/O requirements. The frequency response is Steam turbine control systems internally selectable, as is the master/slave function which allows Process control systems synchronization of multiple IEM-422 transmitters to prevent beat Pulp/paper industry frequencies and cross talk between transducers.
