Johnson Controls MS-FAC3613-0C Metasys Controller

The Johnson Controls MS-FAC3613-0C is an Advanced Application Field Equipment Controller made for the Metasys building automation system. It is perfect for accurately controlling HVAC and other facility equipment in commercial and industrial settings. This controller has a powerful processor, a lot of I/O ports, and quick data persistence, so it can control things on its own and function well with BACnet-based networks.

The MS-FAC3613-0C works as a BACnet Advanced Application Controller (B-AAC) on an RS-485 BACnet MS/TP bus and can run both pre-built and user-programmed applications. It has 16 MB of flash memory, 8 MB of RAM, and a built-in real-time clock that lets it keep track of schedules, calendars, and trend data even when it is not connected to the main Metasys supervisory system.

The controller has a wide range of universal inputs, binary inputs, analogue outputs, and binary outputs, so it can work with many different field devices like sensors, actuators, and relays. It has a small IP20-rated inclosure, can be mounted on a DIN rail or with screws, and has pluggable terminal blocks that make it easy to install and maintain in control panels and equipment rooms.

MS-FAC3613-0 Features:

1) Advanced Application Field Equipment Controller for Metasys systems, great for complicated HVAC and facility control plans.

2) BACnet MS/TP B-AAC device with RS-485 communications for connecting to Johnson Controls and other BACnet systems.

3) Fast persistence lets you keep data values for brief, programmable periods of time, which makes restarting easier and makes data more reliable.

4) An integral real-time clock that lets you use local schedules, calendars, and trending for long periods of time without being connected to a network.

5) A flexible I/O mix with 26 points total: 8 universal inputs, 6 binary inputs, 6 analogue outputs, and 6 binary outputs. This lets you use a lot of different sensors and actuators.

Typical Applications

The MS-FAC3613-0C is good for air handling units, rooftop units, fan coil systems, heat pumps, and other complicated HVAC systems that need to connect to more than one sensor and actuator. Its built-in real-time clock and quick memory make it good for control sequences that need to be scheduled exactly and use historical data, including occupied/unoccupied modes and demand-based ventilation.

The controller’s I/O capabilities allows it to read temperature, humidity, pressure, and flow sensors, as well as control the analog and digital outputs for pumps, fans, valves, dampers, and electric heaters. When used with a Metasys supervisory controller, it forms part of a building automation system that can grow to save energy and make people more comfortable.

Compatibility and Networking

The MS-FAC3613-0C is one of the FAC family members included in Johnson Controls’ Advanced Application Field Equipment Controller catalog, which also lists compatible supervisory devices, network sensors, and software tools. When set up correctly on the BACnet MS/TP trunk, it can work with other Johnson Controls controllers and BACnet devices from other companies to provide a single building automation solution.
