SCC311 is a signal isolator utilized to prevent damage to valuable PLCs, DCS, etc. from fluctuations in the input signal from field devices. It is also a signal multiplier that retransmits 2 output signals from 1 input signal. It accepts input from 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt50, Pt100 as well as Cu53 3-wire RTD sensors, 0 – 50 mV voltage and 4-20 mA or 0 – 20 mA analog current signals. A cost-effective version for AC current/voltage input is also available. SCC311 provides isolation between its own power supply, the input and output signals up to 1 KV AC RMS per minute and 250 V AC RMS continuously. The operator calibrates Zero and Span for the isolator on the front of the unit via membrane keys. SCC311 features a single programmable LED display to indicate the measured signal. Radix can also provide a RS485/MODBUS RTU option for this isolator.
