Isolated DIN Rail Repeater/Splitter for Current Signals

Descrição

The DRSL-SP1 isolated repeater/ splitter provides a competitive choice in terms of both price and technology for galvanic isolation of current signals to SCADA systems or PLC equipment. Two current outputs are provided which mirror the single current input.

The DRSL-SP1 can be used for signal conversion of a standard process current signal into two individual analog signals. The unit offers 4-port isolation, provides surge suppression and protects control systems from transients and noise. The DRSL-SP1 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. Measurement ranges are factory calibrated. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).
