A combination package, which is designed to provide 10-35 VDC
loop powered 4-20 madc isolation, as well as 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.
