Product Description
4-dgt multi-range 碌P-based
controller for temperature
measurements in 擄C or 擄F and
for process signals.
Input from thermoresistance
or thermocouple, PTC, 0/4
to 20mA or 0 to 10VDC. Any
parameter is fully programm-
able by user-friendly key-pad.
The PDI 40 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.
