Product Description
Ordering Key
PDI20A T1 HRX
4-dgt multi-range μP-based
controller
for
measurements in °C or °F and
for process signals.
Input from thermoresistance
or thermocouple, PTC, 0/4
to 20 mA or 0 to 10 VDC. Any
parameter is fully programm-
temperature
able by user-friendly key-pad.
The PDI 20 includes auto-
tuning, direct or reverse PID
control and dynamic setpoint
capability. The housing is easy
to mount and ensures a
degree of protection of IP 54.
