JCI-BUS BACnet

The JDB8410 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 devices JDB8420 and JDB8440 provide the feature of manual override for four 1-state drives. Note: The module contains a connector that can be used to lock the option of manual override, i.e. if a signal is applied here, the positions of the switches have no influence, but the outputs will behave as if all switches would be in the "Automatic" position. However, the 'overridden' flag will be updated, regardless if manual override is locked or released. The JDB8410 module is a DIN rail mountable device and includes the terminals for wiring the physical input and output points and the status and troubleshooting LEDs. The JDB8410 module communicates with the host controller via the controller’s SA (sensor/actuator) bus. Configuring and commissioning of the JDB8410 module is done using the Controller Configuration Tool (CCT). 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 mounted module by an USB-cable. Instead of a JDB8420 front panel, also the rail mounted device JDB8440 can be used. If manual override and signalizing are not required, the JDB8410 can be used without front panel just as additional inputs and outputs for FEC / FAC / NCE controllers.
