Bosch D8129 Octo-Relay Module, Provides 8 Programmable Relays

The D8129 Octo-relay Module is suitable for applications requiring Form C relays to operate auxiliary systems or to display fire system status at remote annunciators. Building components such as HVAC, door lock releases, and stairwell pressurization can interface with the D8129 for complete system control and monitoring.

Industrial, commercial, and institutional facilities are typical installations for the D8129 module. The eight on-board relays can be programmed to activate on system alarm, system trouble, individual zone or point faults, and through remote control by authorized users.

The D8129 Octo-relay Module provides eight programmable Form C relays. Each relay provides dry contact switching rated for 1.0 A at 30 VDC. The relays are accessed through on-board screw terminal connections.

The D8129 uses information from the control panel serial data output to activate the relays. On-board switches are used to configure the D8129 for different operating modes, or to specify relay output numbers. These switches, along with control panel programming options, determine the D8129s response to the serial data. Programming within the control panel can activate specific relays or sets of relays in response to system conditions.

For the G Series control panels, slide switches are configured for specific relay output numbers, which are activated according to their programming. The D8129 uses five slide switches with multiple setting options to configure its mode of operation. The D8129 receives serial data from the control panel and activates relays in response to control panel conditions and slide switch settings. Relays can be programmed for remote control from a panel keypad.
