Digital thermostats—temperature control capabilities play a key role in today’s electric heating monitoring solutions and contribute to ever-increasing standards of safety, reliability, accuracy, and energy efficiency. The temperature range is -60 to +999°C.

Our electronic temperature controllers also comply with the latest Ex protection directives when used in power plants, oil and gas facilities, chemical and petrochemicaland pharmaceutical plants, the plastics industry, wastewater treatment plants, and other typical hazardous areas.

The latest electronic thermostats adapt to the ambient air temperature and respond proportionally to it, rather than simply turning on and off. Eltherm’s selection includes

• thermostats and temperature sensors, ice and snow sensors
• Electronic proportional controllers and limit controllers with Modbus and alarm functions
• Power and control panels for hazardous (e.g.) and non-hazardous areas

ELTC-14

Electronic temperature controller with a digital display for wall mounting. Temperature is measured by a Pt100 sensor. After evaluating the actual and preset values, the appropriate output relays are activated depending on the configuration. Cable glands and terminals are provided for the power connection. The device is supplied in a weatherproof plastic housing with a transparent cover.

• Operating voltage: 90–260 VAC, 50/60 Hz
• Power consumption: Max. 4 mA; <: 5 W
• Switching-capacity relay 1, 20 A, with hybrid relay
• Switching capacity relay 2, 8 A, changeover contact (alarm)
• Operating temperature: -25 to +55 °C
• Storage temperature: -30 to +60 °C
• Display range: -50 to +400 °C
• Adjustable range from 0 to +390 °C, optional configuration
• Sensor connection: Pt100 2-wire, 3-wire, optional configuration
• Display LED, red
• IP rating: IP 65
• Dimensions (W x H x D) 130 x 130 x 75 mm polycarbonate enclosure

Sensors and Display: Two types of sensors can be used: either Pt100/2-wire or Pt100/3-wire – the ELTC-15 can be used with a TC-K (Type K thermocouple) sensor

Optional °C display or °F values.

When using a Pt100/2-wire device, the actual temperature value can be adjusted. The range is +/- 10K or +/- 18F, respectively.

When using a Pt100/3-wire device, the temperature is automatically corrected.

Also compatible with the ELTF-PTEx 1 and 2 sensors.

Relay configuration: Relay 1: controller, Relay 2: alarm / temperature reached

Temperature Alarm: If the actual value differs from the preset limit values, an alarm is triggered and the alarm signal is transmitted via relay K2
