JCI-BUS BACnet

The JDB8452 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 JDB8420 provides the feature of manual override for four 1-state drives. The JDB8420 is a front panel device which can be mounted into the door of a cabinet. On the front panel the state of the inputs is signalized through LEDs and manual override of the outputs can be done with rotary switches. Each front panel device will be connected to its corresponding rail module by an USB-cable. The JDB8452 module is a DIN rail mountable device and includes the terminals for wiring the physical input and output points. The JDB8452 module communicates with the host controller via the controller’s SA (sensor/actuator) bus. Configuring and commissioning of the JDB8452 module is done using the Controller Configuration Tool (CCT). When adding the JxBxx52 devices to the SA Bus in the CCT it is necessary to select the equivalent JxBxx10 model from the SA Bus Device list.
