Siemens RLM162 Air Duct Temperature Regulator

PI temperature controller with modulating and switching outputs for HVAC duct applications

Overview

This is a Siemens RLM162 Air Duct Temperature Regulator, designed to provide accurate temperature control for HVAC duct applications. With a modulating 0-10 V control input, selectable PI control action, and both analog and switching outputs, it offers flexible control capability for heating and cooling sequences.

Key Features

  • Modulating control input: DC 0-10 V for precise setpoint control.
  • Standard operating voltage: AC 24V.
  • Wide setpoint range: Nominal setpoint 0-50°C, with setpoint changeover 0-10 K.
  • Adjustable P-band: 1-50 K.
  • Selectable PI integral action time: 600, 180, or 120 s.
  • Dead zone control: 1.5 K dead zone for heating and cooling in sequence.
  • Flexible outputs: Continuous DC 0-10 V analog control outputs (Y1, Y2) and AC 24-230V, max. 2A switching output (Q13-Q14).
  • Long cable runs: Supports up to 80 m for signal input and switching inputs with 1.5 mm² copper cable.
