Signal Isolator


MSI4P 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 receives 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 linear inputs. MSI4P provides signal isolation of 1500 V AC RMS/1 minute and 250 V AC RMS/continuous between its own power supply, input and output signals. Operators easily calibrate Zero and Span for the isolator via membrane keys on the front of the unit. MSI4P features a single programmable LED display to indicate the process value. A cost-effective version for AC current/voltage input is also available.
