Description

Main features

This electronic temperature controller with the simplest and the most instinctive setting by end user was designed for easy incorporation inside cabinets with DIN rail mounting. It can be used by untrained operators.

It  provides  simple  On  Off  action  temperature  control. End user has access to set point and differential setting only.

It is possible to set °C or °F display, heating or cooling relay output, decimal display, sensor type and temperature range by internal Dip switches (Without access by end user).

Adjustment of maximum temperature can be set without need to open the control.

Dimensions: 86.9 x 58 x 52.5 mm

Display: 3+1 digit LED. The fourth digit is used to display °C or °F, upon setting made.

Set point setting: In normal use, the display shows measured temperature. Push “+” or “-”  keys will display the set point value, and at that time it can be adjusted with “+” and “-” keys. No action during 5 seconds will register the new set point value and bring back display to measured value.

Temperature differential setting: In normal use, the display shows measured temperature. Push “D” key will display the differential value, at that time it can be adjusted with “+” and “-” keys. Push “D” again or no action during 5 seconds will register the new differential value and bring back display to measured value.

Action: On-OFF

Temperature sensor: Pt100 (2 or 3 wires) or NTC 10Kohms @25°C, B= 3380 (2 wires) Temperature sensor can be selected by a dip switch on circuit (No access to final user)

Accuracy: +/-1% of scale

Temperature adjustment ranges:

  • -30+120°C (-20+250°F), with 1° display
  • -30,0 to +40,0°C (-20,0 + 99,9°F), with 1/10° display
  • -30+400°C (-20+750°F), with 1° display

Temperature range and decimal digit can be selected by a dip switch on circuit (No access to final user)

Power supply: 90 to 240V, 50Hz or 60Hz

Relay output: SPNO, 16A250V res., 100.000 cycles. Output Led displays relay position.

Relay action: Heating or cooling, open or close on temperature rise output relay action can be selected by a dip switch on circuit (No access to final user)

°C or °F display: can be selected by a dip switch on circuit (No access to final user)

Maximum possible set point adjustment by user: Push “D” button more than 10 seconds, display shows the maximum temperature that can be set by user. Then it is possible to adjust this value with “+” and “-“. push again on “D” or do nothing during 5 seconds will register the maximum possible setting value and control will comes back to measured valued

Ambiant: -20+60°C, 10-90% RH

Power: <4W

Fail safe safety:

  • If no power supply, relay output contact will open
  • If Pt100 sensor or NTC is broken or not connected properly, relay output contact will open and display will show “EEE”
  • If measured temperature is higher than allowed by the set range, display will show “HHH”
  • If measured temperature is lower than -30,0°C or -20,0°F, display will show “LLL”

Electrical connections:

  • Power input: Neutral, phase, ground, with 2.5 mm² terminals
  • Power output: Neutral, phase, ground, with 2.5 mm² terminals for direct connection to the
  • Temperature sensor:  three 2.5 mm² screw terminal One   removable   jumper   provides   a  potential   free   relay   output   for   applications   needing   a separate   circuit   for   relay,  external   timer   or   other.

Internal parameters setting: Process is given on request to approved distributors. This allows to store only one product and set parameters upon end user request.

Standards: Comply with EMC (CE), ROHS and Reach

Technical informations associated to this product

  • Description of temperature controls

    Used as control thermostats or as a safety thermostat with manual reset, these thermostats have a disc made of two different metals laminated together for temperature sensing element. These two metals have different expansion coefficients.
  • Electrical contacts

    As numerous mechanisms exist, we decided not to distinguish on the basis of constructive technique, but according to their operation speed, which is the key element.
  • Electrical protection classes

    The housings are designed to protect electrical equipment located inside. This protection must be considered in the electrical and environmental angles.)
  • Thermostats installation

    The proper functioning of a thermostat depends primarily on the correct choice of the component, but also the conditions of its installation. Conditions used to calibrate regulating and control equipment in the factory are always ideal laboratory conditions, ensuring measurement accuracy and repeatability. These conditions are rarely those found in practice when installing thermostats. However, with a minimum of constraints, it is possible to optimize assemblies.
