The REG21 controller has two limit contacts for installation in a control panel.
The REG21 is the choice of transistor or relay outputs as limit contacts. It has also a high level of accuracy and long-term stability.
The REG21 has no zero-point drift because of the cyclical self-calibration of the zero-point.It has very little hysteresis, it is largely independent of temperature. It has 4½ digit LED display and the Output signal is 0/4…20 mA or 0…10 V.
The selectable attenuation of the output is up to 10 s. This is the choice of transistor or relay outputs as limit contacts.
