Siemens Control Modules Series (AC 24V)
Universal AC 24V Siemens controller modules for proportional (PI/PID) or step control of parameters in HVAC, ventilation, heating, and cooling systems.
Siemens RWD and RLU (Synco 200) universal control modules are engineered for precise regulation of parameters such as temperature, humidity, pressure, and airflow in building automation systems. Powered by a safe AC 24V low voltage, these modules feature built-in PI/PID algorithms to perfectly control valve actuators, damper motor drives, and frequency inverters. The RWD62 stands out with its proportional analog outputs (0...10V), while the RWD82 offers auxiliary relay contacts for step or on/off configuration. The multi-functional RLU222 controller handles comprehensive ventilation plant (AHU) and primary plant control configurations with its expanded input/output layout.
