- IOM controllers
- The IOM controllers are expansion input and output modules with integral RS-485 MS/TP communications. IOMs can serve in one of two capacities, depending on where they are installed in the Metasys system. When installed on the SA Bus of a CGM, CGE, CVM, CVE, FAC, FEC, or VMA controller, the IOMs expand the point count of these controllers. When installed on the FC Bus, the IOMs support monitoring and control from an NAE or NCE as I/O point multiplexors. The point multiplexor can also be useful for sharing points between other field controllers on the FC Bus using peer-to-peer connectivity. A full range of CGM, CGE, CVM, CVE, FAC, FEC, and VMA models combined with the IOM models can be applied to a wide variety of mechanical and electrical equipment control applications ranging from simple fan coil or heat pump control to advanced central plant management.
- M4-XPM series expansion I/O modules
-
The M4-XPM series input/output (I/O) expansion modules are part of the Metasys system CG, CV Equipment Controller family and can serve in one of two capacities depending on where they are installed in the Metasys system. When installed on the Sensor/Actuator (SA) Bus of a Metasys controller, an XPM expands the input and output interfaces that can be used with that equipment controller. When installed on the Field Controller (FC) Bus of a Metasys network engine, an XPM can be used as I/O point multiplexors to support monitoring and control from a Metasys network engine. The point multiplexor can also be useful for sharing points between other equipment controllers on the FC Bus using peer-to-peer connectivity.
XPMs operate on an RS-485 BACnet MS/TP Bus and are BACnet Testing Laboratory (BTL) listed and certified to the BACnet Smart Actuator (B-SA) profile.
Compatibility:
