PROFILE

The 40T 72 PID is a 72x36 microprocessor
based controller, manufactured with SMT.
The instrument has an operator interface
protected by a lexan®membrane, which
provides an IP65 front face protection.
It is made up of 3 keys, a 4-digit display
and 3 indication LEDs.
Different sensors can be connected to the
input of the variable to be controlled:

• Thermocouples type J, K, R, S, T, B, E, N.

• 3-wire PT100 resistance thermometer.

• PTC thermistor.

• 0…60mV, 12…60mV, 0…20mA,

4...20mA, 0...10V, 2...10V linear signals.
The selection of the sensor is made from
keyboard and through the proper input
contact. No external matching shunt is
required.
Instruments are equipped with 3 relays
(5A, 250Vac, cos

ϕ

=1) or static (6V/20mA)
outputs, which can be used as controls
(heat, cool or heat/cool not without
overlap) and/or as alarms.
A triac output is also available (as an
alternative to two relay outputs) to control
directly resistive loads up to a max. of 2A
by 240V.
The programming of the instrument is
made easy by grouping the parameters in
function blocks (CFG for control parameters,
Inp for inputs, Out for outputs) and by a
simplified data entry menu.

The configuration can be simplified even
further using the PC programming kit made
up of a connection cable and a menu guide
program that runs under Windows (see
technical data code WINSTRUM).
A configurable personal software protection
code (password protection) can be used
to restrict the levels of editing and
displaying the configuration parameters.
