Address Switch

The rotary switch located at S1 sets an RDB’s address. The 16 position is only valid in the 0

through 7 range. Setting an RDB to addresses 8 through F is not defined and should not be used.

NOTES In EX7000-OEM systems that include multiple RDBs, it is imperative that each RDB be set to a

unique address. The address does not have to be in sequential order.

Relay Banks

The EX7000-OEMs relay drive connectors on the RDB are partitioned into three banks: J2

through J5 constitute bank 0, J6 through J10 bank 1, and J11 through J14 bank 2. Although a

single RDB may contain both latching and non-latching devices, the banks may only contain one

type of device. For example, if J2, J3, and J4 are connected to non-latching devices, J5 may only

contain a non-latching relay. A latching relay could, however, be installed in J6.
