It supports BACnet IP as the backbone bus, MS/TP and Sylk bus for wall-module integration, and Modbus for third-party device interfacing. Supplied with 24 VAC power input, the controller includes 7 universal inputs/outputs configurable as analog or binary and 5 SSR outputs for high-current switching. The integrated actuator offers 44 in-lb (5 Nm) torque and supports 90 sec runtime at 60 Hz. Its built-in field-replaceable differential pressure sensor enables pressure-independent VAV performance. Key Features: Seven Universal Inputs/Outputs (UIO): Configurable for voltage, current, binary or pulse signals to handle diverse building automation tasks. Five Solid-State Relay (SSR) Outputs: High-reliability switching outputs for fans, actuators or other loads without mechanical wear. Integrated Actuator & Airflow Sensor: Built-in damper actuator with feedback and replaceable differential pressure sensor for accurate VAV control. BACnet IP & MS/TP Network Communications: Supports IP backbone (10/100 Mbps) and MS/TP for flexible integration into contemporary BMS architectures. Sylk™ Bus & Modbus Client Support: Facilitates connection to Honeywell Sylk wall modules and Modbus devices for extended system interoperability. Bluetooth Low Energy (BLE) Support: Enables mobile device commissioning, balancing and diagnostics without opening the ceiling plenum. 24 VAC Power Supply with Auxiliary 20 VDC Output: Standard building supply voltage with onboard auxiliary output to power field devices. High Application Flexibility: Programming via Niagara 4 platform, enabling custom control logic and free-programmability for advanced HVAC sequences. Field-Replaceable Pressure Sensor: Differential pressure sensor (±500 Pa span, ±3% accuracy) allows quick service or retrofit without replacing the entire controller. The CLMEVA75IB24NM delivers the control capability, network connectivity and serviceability required for high-performance modern VAV installations.
