Information About MS-IOM2721-0
The MS-IOM2721-0 is part of the Johnson Controls Metasys® IOM27 Series of field input/output expansion modules developed for commercial building automation applications. It expands the available field interfaces of compatible Field Equipment Controllers (FEC), Field Application Controllers (FAC), Variable Air Volume Modular Assemblies (VMA), Network Control Engines (NCE), Network Automation Engines (NAE), System Network Controllers (SNC), and System Management Controllers (SMC) by providing additional analog and digital input/output capacity. The module communicates over an RS-485 BACnet MS/TP network and may also connect through the SA Bus, allowing seamless integration into both Johnson Controls and third-party BACnet systems. Powered from a nominal 24 VAC source, it incorporates a 32-bit Renesas® RX631 microcontroller, onboard flash memory, and programmable configuration for reliable long-term HVAC monitoring and control.
Key Features:
- Eight Universal Inputs: Supports 0–10 VDC, 4–20 mA, resistive sensors, and binary dry-contact inputs.
- Two Analog Outputs: Provides configurable 0–10 VDC or 4–20 mA control outputs.
- BACnet MS/TP Communications: Integrates directly with Metasys® and compatible BACnet automation systems.
- 24 VAC Operation: Compatible with standard HVAC control transformers.
- Flexible Controller Expansion: Extends compatible Metasys controllers without replacing existing hardware.
- 32-Bit Processing Platform: Utilizes a Renesas® RX631 microcontroller for dependable field operation.
- DIN Rail or Surface Mounting: Supports quick installation using integrated mounting clips.
- Commercial HVAC Applications: Suitable for air handling units, central plants, packaged equipment, and other building automation systems.
The MS-IOM2721-0 delivers the reliability and precision required for expanding analog and digital field input/output capacity in commercial HVAC and building automation systems.
