Part number C550SQN-1C from Johnson Controls, listed in Valves & Process Control. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls C550SQN-1C is a System 550 expansion module engineered to increase the control capabilities of the System 550 modular electronic control platform. It provides two additional analog outputs, enabling precise, proportional, or proportional-plus-integral management of connected HVACR equipment. This module allows commercial and light industrial building automation systems to scale control configurations according to specific application demands. Features Expands the System 550 platform by adding two analog outputs. Proportional or proportional-plus-integral control modes for precise modulation. Part of a flexible, mix-and-match modular architecture supporting up to 10 total outputs when combined with other expansion modules. Compact design for easy, plug-in integration into existing System 550 setups. Designed to meet high commercial standards for HVACR system longevity and reliability. Specifications Brand: Johnson Controls Model/MPN: C550SQN-1C Series: System 550 Module Type: Output Expansion Module Outputs: 2 Analog Outputs Output Modes: Voltage Mode (0 to 10 VDC, 10 mA max, requires load >= 1000 ohms) or Current Mode (4 to 20 mA, requires load < 300 ohms) Enclosure Type: IP20 high-impact thermoplastic Dimensions: 5.09 inches Height x 2.40 inches Width x 2.70 inches Depth Weight: Approximately 0.39 lbs Applications The C550SQN-1C is designed for commercial and light industrial HVACR applications requiring staged or modulated multi-stage control sequences. By delivering dual analog outputs, it allows building automation systems to regulate proportional equipment such as fans, valves, and damper actuators. It is commonly utilized in supermarkets, cafeterias, convenience stores, data centers, greenhouses, and commercial building management systems.
