JCI-BUS BACnet

The JAB0451 is an output expansion module compatible with the Johnson Controls Metasys® FEC family of field equipment controllers. It is designed to provide additional analog outputs (0-10 VDC) for FEC, FAC and NCE controllers. The device JAB0451 provides integral manual overrides for the analog outputs, selected by 3 position switches and the output VDC signal adjusted by rotary potentiometers. The status of the outputs is indicated by the variable brightness LEDs. The JAB0451 module is a DIN rail mountable device and includes the terminals for wiring the physical output points, the manual overrides and the status and troubleshooting LEDs. The JAB0451 module communicates with the host controller via the controllers SA (sensor/actuator) bus. Configuring and commissioning of the JAB0451 module is done using the Controller Configuration Tool (CCT). When adding the JxBxx51 devices to the SA Bus in the CCT it is necessary to select the equivalent JxBxx10 model from the SA Bus Device list.
