Find the Right SSI Product
SSI pulse metering products from Radian Research carry energy pulses from revenue meters to the systems that use them: SCADA, energy management, load control, and customer billing. Pulse isolation relays protect the meter’s output and split it to several users, totalizers add pulses from many meters, and pulse links send them across a site by fiber, radio, or current loop.
Use the selection chart below to compare every current model. Key: A = Form A (2-wire), C = Form C (3-wire), A or C = field selectable.
