EC 4-173 is a digital one output P.I.D. temperature controller designed to cover a temperature range from 0 to +999 °C, meeting the needs
of a wide part of the applications of accuracy in heating field.
In factory, the instrument gets set to accept, at the input, "J" (Iron-Constantan) or "K" (Chromel-Alumel) thermocouples and is provided of a
"Auto-tuning" function activable through a key located on the front panel of the instrument, it is studied to permit the instrument to compute
the optimal value of the parameters used during the temperature regulation, in order to use them during the conclusive part of the regulation.
The SPDT relay-output can manage (up to) 8 A loads at 250 Vac and it is supplied in standard version; as option it is possible to request an output
with low-voltage signal, suitable to drive the SSR modules (solid state relay).
The flashing signals on the display have been studied in order to catch user's attention in case of not proper functioning: defective probe, temperature
outside the limits permitted by the used probe or corrupted memory-data.
The instrument is provided of one temperature alarm that can be disabled, configurable in six different ways of working; the intervention of the
alarm determines the appearing on the display of the indication "AL1" alternated to the temperature read by the probe.
* 3 digits display, height 12,5 mm.
* P.I.D. temperature regulation.
* "Auto-tuning" function studied to compute the
optimal value of the parameters used during the
temperature regulation.
* 1 widely configurable temperature alarm.
* 1 relay-output (8 A at 250 Vac).
