A range of Input/Output modules compatible with Metasys. IOMs can serve in one of two capacities depending on where they are installed on the Metasys system. When installed on the Sensor Actuator (SA) Bus of an Field Equipment Controller (FEC), the IOMs expand the point count of these controllers. When installed on the Field Controller (FC) Bus as point multiplexers, IOMs allow a Network Automation Engine (NAE) or Network Controller Engine (NCE) to monitor and control supervisory points directly. A full range of FEC/FAC models combined with the IOM models can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control, to advanced central plant management. Features Expands controllers for larger applicationsFlexible configurations: 4, 6, 12 and 17-point expandabilityIntegrates at both field and supervisory levelsModels with 16 inputs for monitoring applications
