MS-IOM3721-0

|

The MS-IOM3721-0 Input/Output Module by Johnson Controls increases input/output points for HVAC equipment management, which is a crucial part of industrial automation. It can tolerate temperatures between 0°C and 50°C while running on 24 VAC with a 14 VA maximum usage. Integration is made possible via BACnet MS/TP support over RS-485, and effective data processing is ensured by a 32-bit microcontroller with 640 KB Flash and 128 KB RAM. It is essential for accurate control and monitoring thanks to its 16 binary inputs and IP20-rated housing.

The MS-IOM3721-0 Input/Output Module from Johnson Controls's Metasys® system Field Equipment Controller family is an essential feature of many automated manufacturing processes. Its goal is to improve HVAC monitoring and control by increasing the number of input/output connections to controllers like NAE, NCE, FAC, FEC, and VMA. The module is designed to function reliably and efficiently while using a minimum of power (14 VA) from a 24 VAC source. It can keep working dependably in a wide range of temperatures, from freezing to boiling. DIP switches are used for the addressing system, and addresses from 4 to 127 are allowed for controller devices. It is compatible with Johnson Controls® and other BACnet systems thanks to its RS-485 bus compatibility for BACnet MS/TP communications. The H8SX/166xR Renesas 32-bit microcontroller has enough storage and processing power thanks to its 640 KB Flash Memory and 128 KB RAM. This module has 16 binary inputs that may be set to either pulse counter/accumulator mode or dry contacts maintained. The ABS and polycarbonate housing is plenum-rated and self-extinguishing for maximum protection. The connections and mounting clips are included in the unit's compact 150 mm x 164 mm x 53 mm design, and it has a protection level of IP20 (IEC529) for maximum insulating efficiency. The fact that it just weighs 0.5 kg is a major plus as well. Industrial automation experts may improve HVAC system control and monitoring with the help of the MS-IOM3721-0 Input/Output Module, a flexible and dependable piece of equipment.
