MS-IOM4711-0 Johnson Controls

Overview

The Johnson Controls MS-IOM4711-0 is a versatile 17-point Input/Output Module (IOM) designed to expand the point capabilities of Metasys system field controllers, such as FECs, FACs, and VMAs. Operating on a 24 VAC supply via the RS-485 BACnet MS/TP protocol, it integrates seamlessly into both Johnson Controls and third-party Building Automation Systems (BAS). It can reside on either the Field Controller (FC) Bus as a supervisory point multiplexer or on the Sensor/Actuator (SA) Bus to provide flexible monitoring and precise control over a wide variety of HVAC and industrial automation equipment.

Features

• 17-Point Expandability: Features a highly flexible point configuration consisting of 6 universal inputs, 2 binary inputs, 2 analog inputs, 3 binary outputs, and 4 configurable outputs.
• Dual Bus Versatility: Can be installed on either the FC Bus or the SA Bus depending on system monitoring and expansion requirements.
• Standardized Hardware and Software: Uses a common platform design to support consistent wiring workflows and single-tool commissioning.
• Advanced Microprocessor and Memory: Equipped with a 32-bit Renesas microcontroller, 512 KB Flash memory, and 128 KB RAM for efficient data processing.
• Robust Enclosure: Housed in a durable, self-extinguishing ABS and polycarbonate plenum-rated enclosure featuring an integral end-of-line (EOL) switch.

Specifications
