• 4-20 Ma Control Loop Isolator, Surge Suppressor And EMIRFI Filter

This is a multi-function product that provides current loop isolation, industrial surge suppression and effective EM I/ RFI noise filtering for 4-20 ma control loop applications. An advanced design 10-35 VDC loop powered 4-20 madc isolator designed around galvanometric-based technology provides 1500 VRMS of instantaneous isolation. Accuracy to within ± 0.1%, Linearity better than 0.01%. Adds 15 ohms ± 10% to the control loop.


The surge suppression portions of the circuit are designed to protect sensitive process control equipment and instrumentation from proximity lightning strikes and other transient sources. The multi-stage design utilizes gas ionization-based technology as the primary stage of protection. The secondary stage incorporates a high-speed transient voltage suppression (TVS) circuit.


EMI / RFI noise filtering is accomplished via a broadband passive noise filter. The proprietary common mode filter circuit provides effective elimination of undesirable noise and EMI/RFI from 0.1 Hz to 50 Mhz.
