EVK402
|
EVK is a range of one (EVK 401/411/421/402) or two outputs (EVK 412/403) configurable digital universal regulators able to work in a working range between -100 and 1300 °C. EVK402/403 models have got one more alarm output.
One output instruments are able to work for "heating" or "cooling" regulation with possibility of defrost management (by stopping the
compressor) when configured for "cooling" regulation.
2 outputs instruments are able to work in 4 working modalities: with two independent working setpoints, with one independent and one
relative working setpoint, with "neutral zone" or with "steps".
Thanks to availability of models with universal measure input (for "J" or "K" thermocouples, PTC or NTC or 2/3 wires Pt100/Pt1000/Ni 120
probes, 0/4-20 mA transducers 0-10V / 2-10V), to the availability of different power supply and to temperature reading scale configuration (°C or °F), these controllers can be defined "universal devices for temperature control".
EVK421 and EVK402 models also have a multifunction digital input configurable for load protection, Energy Saving or alarm activation.
