Johnson Controls MS-IOM2721-0 Expansion Input/Output Module for FX-PCX2721-0 [New]

The IOM2721 input/output expansion module is part of the Metasys system Field Equipment Controller family
Input/Output expansion modules (IOMs) expand the number of Input/Output points connected to either a SMC, SNC, Network Automation Engine (NAE), Network Control Engine (NCE), Advanced Application Field Equipment Controller (FAC), Field Equipment Controller (FEC), or Variable Air Volume Modular Assembly (VMA) to monitor and control a wide variety of HVAC equipment.

IOMs operate on an RS-485 BACnet?« MS/TP Bus and integrate into Johnson Controls?« and third-party BACnet systems. IOMs communicate using the BACnet MS/TP protocol when directly connected to the FC Bus.

Note: With Release 10.1 or later of the Controller Configuration Tool (CCT), VMAs, FECs, and FACs can be configured to communicate using either the BACnet MS/TP or the N2 field bus networking protocol. The operation of the IOM is not affected by the selection of the BACnet MS/TP or the N2 protocol in the host controller, when the IOM is connected to the host controller using the SA bus..
