Two-point Controller ZPR-21
Adjustable switching points
The two-point controller is activated by an analogue signal of 0 - 10 V. The switch-on and switchoff point of the controller can be set individually by
the integrated potentiometers.
• AUTO-OFF-ON with feedback
The coupling module can switch to automatic or
manual mode. In automatic mode the contact with
feedback is closed; therefore a logic 1 results on
the controller. Multiple feedbacks can be connected in series.
• DIN 45 mm housing
The standardised housing enables the coupling
module to be installed by means of a 45 mm cutout behind the covering; it only requires a width of
17.5 mm for this
