The 420TWRTD isolating terminal block can replace standard DIN-rail terminals to provide input isolation, signal conversion and excellent RFI and noise rejection.
The units are powered from the output side, making them ideal for plc and data acquisition applications.
Inputs for the 420TWRTD are 2 or 3 wire PT100 type sensors, other units are available for thermocouple, current and voltage inputs and the standard output is an output powered 4-20mA.
The units can be factory or user configured for virtually any type of RTD PT100 2 or 3 wire inputs.
A typical wiring arrangement is shown opposite.
In addition two digital modules are available allowing the isolation of digital inputs and outputs.
The devices are housed in ultra-compact DIN rail mounted enclosures from only 12.5mm wide.
