PRESENTATION
N323TR is a temperature controller suitable for refrigeration, with
functions designed for temperature control applications and
optimization of the defrosting process.
Its internal clock allows you to program defrost times and days.
It has 2 input channels for temperature sensors (NTC thermistors)
that measure the temperature of the monitored environment and the
evaporator module.
It has 3 independent outputs to control the compressor (refrigeration
output), the defrost module, and the fan.
The details of the controller are in accordance with the purchase
order and are shown on the label attached to the controller.

SPECIFICATIONS
SENSOR INPUT:
2 NTC Thermistors: Type 10 kΩ @ 25 °C | Measurement range:
-50 to 120 °C (-58 to 248 °F) | Accuracy: 0.6 °C (1.1 °F).
Note: The sensors are supplied with the equipment.
Its operating range is -30 to 105 °C (-22 to 221 °F). It has a 3 m
long cable (2 x 0.5 mm²), which can be extended up to 200
meters.
Maximum error when interchanging original NTC sensors: 0.75 °C
(33.35 °F). This error can be removed by using the Offset
parameter of the controller.
Measurement resolution: ........ 0.1 °C in the range -19.9 to 199.9 °C
........................................................................... (-3.8 to 391.8 °F).
............................................................................ 1 °C: Elsewhere.
Note: The equipment maintains accuracy over the entire range,
although the low resolution of the display in a portion of the range
does not allow it to be visualized.
OUTPUT1: .............................................. SPDT Relay; 1 HP 250 Vac /
.................................................... 1/3 HP 125 Vac (16 A Resistive)
Optionally: ..................................... Pulse, 5 Vdc, 25 mA maximum
OUTPUT 2: ........................................... SPST-NO relay, 3 A / 250 Vac
OUTPUT 3: ........................................... SPST-NO relay, 3 A / 250 Vac
POWER SUPPLY:
Voltage:................................................. 100~240 Vac/dc (± 10 %)
Optionally: ..................................................... 24 V (12~30 Vdc) (*)
Frequency: ...................................................................... 50~60 Hz
Consumption:.......................................................................... 5 VA
(*) Note: Models with a 24 V power supply do not have electrical
isolation between the power supply, input, and RS485
communication circuits.
In direct current (Vdc) supply networks, you must observe the
polarity of the connection.
Dimensions:
