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).
