JCI-BUS BACnet

The JDB6451 is an input/output expansion module compatible with the Johnson Controls Metasys® FEC family of field equipment controllers. It is designed to provide additional inputs and outputs for FEC, FAC and NCE controllers. The device JDB6451 provides the control of two 2-state drives with integral manual overrides for the binary outputs selected by 3 position switches for selecting manual/off/auto status and 2 position switches for selecting output state 1 or 2 (e.g raise/lower). The binary outputs of state 1 and 2 are interlocked. When changing from one state to the other in auto mode, a short-time delay between the two states should be configured in the application. The state and fail status of the corresponding inputs is indicated by the LEDs, the fail indication LEDs are user defined red or green. The 6 Binary Inputs can also be configured independently as additional physical points for the host controller. The JDB6451 module is a DIN rail mountable device and includes the terminals for wiring the physical input and output points, the manual overrides and the status and troubleshooting LEDs. The JDB6451 module communicates with the host controller via the controllers SA (sensor/actuator) bus. Configuring and commissioning of the JDB6451 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.
