Description

The DRSL-TEMP isolated DIN rail loop-powered temperature signal conditioner measures a standard type J or K thermocouple or a 2-, 3- or 4-wire Pt100 RTD temperature sensor and provides a passive analog current output signal.

The DRSL-TEMP offers 2-way isolation between input and output, provides surge suppression and protects control systems from transients and noise.

The DRSL-TEMP provides a competitive choice in terms of both price and technology for interfacing thermocouple or RTD signals to SCADA systems or PLC equipment. This unit is powered by the host (output) current signal loop. Low power consumption facilitates DIN rail mounting without the need for any air gap. Easy configuration of more than 1000 factory calibrated measurement ranges is done via DIP-switches. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).
