NTC thermostat ET5411

digital

ET5411; 54x94mm sized. On-Off control. Relay output for cooling or heating control. Single NTC probe input. Offset value can be entered for NTC probe. In the case of probe failure, output state can be selected as on, off or periodical running. Upper and lower limits of the setpoint can be adjusted. Temperature unit can be selected as °C or °F. C RS485 ModBus protocol (optional). CE marked according to European Norms. ommunication feature ov Outputs Relay output - For ET5411-X-X ; Relay: NO+NC 250V AC, 8A (for resistive load), 1/2hp 240V AC (for inductive load) For ET5411-X-P ; Relay: NO 277V AC, 20A (for resistive load), 2hp 250V AC (for inductive load) Environmental Conditions Ambient/Storage Temperature - 0...50 ºC / -25...70 ºC Relative Humidity - 80% relative humidity for temperatures up to 31 °C, decreasing linearly to 50% at 40 °C Protection Degree - According to EN 60529 Front panel: IP65, Rear panel: IP20 Height - Max. 2000m Electrical Characteristics Supply - 230V AC +10% -20% 50/60Hz or 12/24V AC/DC ±10% Power Consumption - 5VA External Connections - Screw-terminals Scale - -60.0...150.0 °C Sensitivity - 0.1°C (selectable 0.1 ºC or 1 ºC) Accuracy - ± 1% (of full scale) Output Relay - 8A model: 250V AC, 8A (for resistive load), NO+NC 1/2hp 240V AC (for inductive load) 16A model: 277V AC, 20A (for resistive load), NO 2hp 250V AC (for inductive load) Life Expectancy - 8A model: Mechanical 30.000.000 operations (under no load), Electrical 100.000 operations (8A at 250V AC, resistive load) Life expectancy for relay - For ET5411-X-X ; Without load 30.000.000 mechanical;
