Quality measurement and good equipment are very important parameter to achive Signal integrity. However, even with the best equipment, signals can be of inferior quality if the equipment is not properly installed or it is not protected by signal isolators / signal conditioners.
Radix design competency in signal isolation is one of the finest to be found. Radix signal isolators are an outstanding combination of accuracy, frequency response and signal handling. Choose from loop-powered isolators which require no external power supply and have very low loop drops, 3-port signal isolators which not only isolate input signals, but also act as signal multipliers and multiply signals to send to multple field instruments. Some of our signal isolators are HART compatible for effortless two-way field communication, that is achieved through superimposition of digital communication on top of the 4-20 mA signal.
Signal isolation devices are use to eliminate ground loop errors caused by noise (ground) and other such signal interference problems.
Signal isolators use one of many electronic methods to interrupt the connections between two grounds while passing the correct signal with little or no loss of accuracy. Without a way for ground currents to flow, these currents can't induce signal errors caused by ground noise.
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.

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.
