Siemens RWF55.50A9 universal burner combustion controller

Description

Siemens RWF55.50A9 universal combustion controller, 96x48mm, 3-pos output, analog output & Modbus

The RWF55 is a modulating burner/boiler control designed and engineered specifically for burner/boiler
applications.

The RS-485 Modbus RTU communications port allows the RWF55 control to communicate with a Building Management System (BMS) or function as an integral part of a PLC or BMS based lead/lag boiler room management system.

The RWF50/55 are used primarily for the control of temperature or pressure in boilers. Whether used independently or as part of an entire Siemens combustion control system, RWF5 units optimize temperature or pressure control on modulating burners.
