DRSL DC4 DIN Rail Signal Conditioner for Bipolar Process Inputs 12985

 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.

 
The DRSL-DC4 also eliminates ground loops and can be used for measuring floating signals. Low power consumption facilitates DIN rail mounting without the need for any air gap. Factory calibrated measurement ranges are easily configured via DIP switches. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).
