RWD62
Universal Controller
For comfort control in HVAC&R-Systems
· Standalone electronic universal controller with P or PI response
· Operating voltage in accordance to type AC 24 V
· Control application selectable via Application Number
· Active input scale can be selectable
· Limit and direction of the output scale is able to be freely assigned
· Two universal inputs for Ni 1000, Pt 1000 temperature sensors and
DC 0...10 V signals
· Unit can be set as °C, °F, % or no specified unit
· Two modulating outputs with DC 0...10 V signal outputs, direct or reverse
action
· One digital input for day/ night changeover
· Entering or changing of all data via operating buttons on the controller, possi-
ble without additional tools
· PC connection for downloading canned applications via the software tool
The universal controllers are intended for Heating, Ventilating, Air-Conditioning and
Refrigeration in comfort control plants. It can be mounted in a control panel or in the
ARG62.21/ARG62.22 housing on ducts, walls and in plant rooms.

Page 7: Installation Notes
Standard cables can be used for the controller. However, when mounting in an envi- ronment greatly exposed to EMI, use only shielded cables. The RWD62 is designed for AC 24 V operating voltage. The low voltage must comply with the requirements for safety extra-low voltage (SELV) as per EN 60730. - Page 8 Screw terminals for cables with min. 0.5 mm dia.
