TER-4

Description

TER-4 | Double thermostat

• Double thermostat for temperature monitoring and regulation over a wide range of temperatures
• Temperature range switch and fine temperature setting for each thermostat
• Usable for temperature monitoring in switchboards, heating or cooling systems, motors, liquids, open spaces, etc.
• Galvanically isolated power supply AC 230V
• 2 inputs for temperature sensors NTC 12k / 25°C
• Setting independent or dependent thermostat function (see function description)
• Short-circuit monitoring or sensor interruption
• Heating / cooling function selection
• Adjustable switching hysteresis (sensitivity)
• Two output relays (for each level independent)
• Output contact 2x switches 16A / 250V AC1
• Output status indication and LED sensor fault indication
• 3-MODULE, DIN rail mounting
• Choice of external temperature sensors (NTC thermistor) with double insulation in standard lengths of 3, 6 and 12m.
