SI4P is a Signal Isolator, that is used to prevent damage to valuable PLCs, DCS, etc. from fluctuations in the input signal from field devices. SI4P is factory-set to accept input from either of 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt1000, Pt200 & Pt100 3-wire RTD sensors, DC voltage and DC current signals as well as resistance input. Special versions can also be ordered in sufficient order quantity for load-cell input. SI4P provides isolation between its own power supply, the input and output signals up to 1.5 KV AC RMS per minute and 250 VAC RMS continuously.

• SCC301 is a dual purpose, current-to-current converter with 3-port isolation. It provides a fully floating, isolated DC supply for energising a conventional 2 or 3-wire 4~20mA transmitter/ smart transmitter and repeats the current in another isolated circuit or accepts a 4~20mA signal from a controller/source to drive loads up to 750 ohms.
• A 20~35VDC power supply is required for operation. The power supply terminations are at the top of the unit to enable this model to be used either as a repeater power supply or driver.
