DPT2650-2R5D-AB Johnson Controls Pressure Transmitter

Overview

The Johnson Controls C450CPW-100C is a professional-grade System 450 control module designed to provide reliable, scalable, and digital electronic control for variable-speed EC motors. It features a built-in Liquid Crystal Display (LCD) and a four-button touchpad user interface. This hybrid analog output control module allows users to configure a custom system that transitions between a pulse output and a standard VDC output depending on the sensor value, providing precision speed control.

Features

• Compact modular design with plug-together connectors that eliminate field wiring between modules.
• Backlit LCD and four-button touchpad user interface for easy configuration and monitoring.
• Field-configurable functionality supporting up to three inputs and up to ten outputs when connected to expansion modules.
• Hybrid analog output capability (specifically on OUTA1) allowing pulse-width modulation or standard VDC/mA control.
• High input signal selection and differential control options.
• Versatile mounting options suitable for DIN rail or direct wall surfaces.

Specifications

• Supply Power: 24 VAC Class 2 / SELV (external) or via C450YNN-1 Power Supply Module (internal).
• Power Consumption: 1.3 VA maximum using 0-10 VDC output; 1.5 VA maximum using 4-20 mA output.
• Input Signals: Supports 0-5 VDC for humidity/pressure, 0.5-4.5 VDC for ratiometric transducers, and A99 PTC/Nickel temperature sensors.
• Analog Output Modes: Voltage mode (0-10 VDC, 10 mA max, >=1000 ohm load) or Current mode (4-20 mA, 0-300 ohm load).
• Ambient Operating Temperature: -40 to 66°C (-40 to 150°F) for 0-10 VDC outputs; -40 to 40°C (-40 to 104°F) for 4-20 mA outputs.
• Operating Humidity: Up to 95% RH non-condensing.
• Enclosure: Type 1, IP20 high-impact thermoplastic.
• Dimensions: 127 x 61 x 61 mm (5.0 x 2.4 x 2.4 inches).

Applications

• Variable-speed EC motor speed control in HVAC/R commercial and industrial systems.
• Proportional and digital control loops for commercial heating and cooling applications.
• Simultaneous management of temperature, relative humidity, and static pressure conditions.
• Custom modular control configurations requiring standalone or multi-stage expansion logic.
