Description
Johnson Controls C450SQN-4 Expansion Module Overview
The Johnson Controls C450SQN-4 is an expansion module designed to extend the input/output capabilities of the C450 Series electronic controllers. By adding 0-10 VDC and 4-20 mA analog signal support along with 2PI (two-point input) functionality, this module enables seamless integration with a broad range of HVAC sensors, transmitters, and building automation system (BAS) devices. It is an ideal solution for commercial and light industrial applications where precise analog signal management and scalable control are required.
Key Features
- Expansion module compatible with Johnson Controls C450 Series controllers
- Supports 0-10 VDC analog output/input signals for broad device compatibility
- 4-20 mA analog signal support for long-distance, noise-resistant signal transmission
- 2PI (two-point input) capability for flexible sensor and device interfacing
- Extends the native I/O capacity of C450 controllers without replacing the base unit
- Designed for commercial HVAC and building automation applications
- Compact form factor for easy installation alongside the host controller
Application & Compatibility
The C450SQN-4 expansion module is engineered for use with Johnson Controls C450 Series electronic controllers, which are widely deployed in commercial HVAC systems for controlling air handling units, fan coil units, VAV systems, and other mechanical equipment. The addition of 0-10 VDC and 4-20 mA I/O channels allows technicians and engineers to connect pressure transducers, humidity transmitters, CO2 sensors, and other analog field devices directly to the controller platform, reducing the need for additional standalone controllers or signal converters.
Why Choose the C450SQN-4
- Maximizes the value of existing C450 Series controller investments
- Simplifies wiring and commissioning with industry-standard analog signal types
- Improves system flexibility and scalability for complex HVAC control strategies
- Backed by Johnson Controls engineering and quality standards
- Reduces installed cost by expanding I/O on a proven controller platform
