The SEM1200 MKII isolated current loop splitter takes a single passive 4-20mA input and provides two independent, galvanically isolated 4-20mA output signals — ideal wherever a single field transmitter reading needs to feed two separate destinations, such as a control system and a local indicator or recorder. Each output loop is externally powered and isolated to a nominal 500 VDC between ports, protecting downstream instrumentation from ground loop currents and interference.
Housed in a compact DIN-rail mounted enclosure, the SEM1200 MKII requires no user adjustment during commissioning beyond an initial operational check. Front-panel zero and span potentiometers are provided for each output channel, allowing independent fine calibration on site. High accuracy and dependable galvanic isolation make it a proven choice for splitting critical 4-20mA signals across oil & gas, water treatment, and general process industries.
