The RWD62 universal controller is an independent electronic controller with P and PI response for comfort control in HVAC and refrigeration systems. It has AC 24 V operating voltage, application programs that can be selected by application number, input value segments that can be selected, output value ranges and directions that can be set arbitrarily, two universal input points for Ni 1000, Pt 1000 resistance temperature sensors and 0…10 V signals, units that can be set to °C, °F, % or undesignated units, two analog output points that output DC 0…10 V signals (can be either positive or negative), a digital input point for day / night setting switching, and the ability to access or change all data via the controller buttons and download pre-made application programs via software.
The RWD62 is a stand‑alone universal controller designed for HVAC and refrigeration comfort applications. It supports P and PI control, selectable input ranges, and configurable output direction. Two universal analog inputs accept Ni 1000, Pt 1000 temperature sensors or 0‑10 V DC signals, and a digital input handles day/night switching. Two analog outputs provide configurable 0‑10 V DC signals for actuators.
Installation can be performed on a DIN rail, inside a protective wall‑mounted housing (ARG62.21/ARG62.22), or by front‑mounting with screws. The controller is powered from AC 24 V (±20 %) and features an LCD display, three operation keys, and a 9‑pin communication port for software configuration. Technical data include a power consumption of 2.5 VA, measurement ranges of –50 °C to +150 °C (or –20 °C to +180 °C), and an IP20 enclosure rating. This manual is written in Chinese.
