• 4-20 Ma Isolator And EMIRFI Filter IP-230-D

A combination package, which is designed to provide 10-35 VDC loop powered 4-20 madc isolation, as well as industrial surge suppression in a single package. Current loop isolation is provided by galvanometricbased technology. The isolator provides 1500 VRMS of instantaneous isolation. Accuracy of ±0.1%, with linearity better than 0.1%. Adds 15 ohms ± 10% to the control loop. The surge suppression portions of the circuit is designed to protect sensitive process control equipment and instrumentation from proximity lightning strikes and other surge sources. The multi-stage design utilizes gas ionization-based technology as a primary protection stage. A secondary stage incorporates a high-speed transient voltage suppression (TVS) circuit. The final stage employs ultra-fast thermal-based circuit breakers with an auto-reset capability. This final stage, not only supports the primary and secondary stages of protection, but will also provide equipment protection from mis-wiring or equipment failure that may introduce high voltage onto the control loop.
