Bipolar Isolated DIN Rail Signal Conditioner for Process Signals
The DRSL-DC4 bipolar isolated DIN rail signal conditioner provides a competitive choice in terms of both price and technology for galvanic isolation of process voltage or current signals to SCADA systems or PLC equipment. The DRSL-DC4 can be used for signal conversion of standard bipolar analog process signals into unipolar analog signals. The unit offers isolation between input, output and supply, provides surge suppression and protects control systems from transients and noise.
