GENERAL
Microprocessor controller in 48x48 (1/16
DIN) format manufactured with SMT.
The instruments have an operator interface made up of 3 keys, a double 3-digit
(500) or 4-digit (501) display and 3 indicator LEDs, protected by a Lexan membrane to IP54.
The input section for the measured variable offers the choice of different sensor
types:
Thermocouples type J, K, N, S, R, T
Resistance Thermometer Pt100 (3-wire)
Linear inputs:
0-50mV, 10-50mV faceplate configurable
2-10V, 0-10V, 0-20mA, 4-20mA with
external shunt.
The instruments have two relay outputs
(5A, 250Vac with cosj = 1) or static PNP
(24Vdc, 20mA).
The first output is changeover and is
dedicated to the control output.
The second is a programmable alarm.
In alternative to the relay control output,
it is possible to have an analogue output
0-20mA, 4-20mA or 0-10V, 2-10V.
The programming of the instrument has
increasing levels of complexity and the
various parameters are grouped in three
different layers.
With increasing value of the programmable protection code, it is possible to place
lower limits on the access of the operator
to modify the configuration parameters.
A hardware jumper removes the possibility to enter into the configuration.
