Input
The 420TW series of isolating terminal blocks can replace standard DIN-rail
terminals to provide input isolation and signal conversion.
The units are powered from the output side, making them ideal for PLC and data
acquisition applications.
Inputs available include thermocouple, RTD, current and voltage and the standard
output is 4-20mA.
For thermocouple inputs, internal rotary switches allow the user to select virtually
any type of thermocouple and the temperature range required.
A typical wiring arrangement is shown opposite.
The device is housed in an ultra-compact DIN-rail mounted enclosure only
18mm wide.
Input types
The 420TW device can accept J, K, T, R, S, E and N type thermocouples. The RTD
input accepts a PT100 2 wire sensor.
