DRSL SP2 DIN Rail Isolated Repeater Splitter for Process Signals 12991

 The DRSL-SP2 isolated signal conditioner/splitter 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. Two process outputs are provided which mirror the single process input.

 
The DRSL-SP2 can be used for signal conversion of standard process voltage or current signals into two individual analog signals. The unit offers 4-port isolation, provides surge suppression and protects control systems from transients and noise. The DRSL-SP2 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. When the input is configured for 2-wire transmitter mode, the DRSL-SP2 provides the current loop supply voltage. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).
