4-Port Expansion Module

Optional Expansion Module

Optional Expansion Modules are available for applications requiring more than the maximum allowable Remote Lockout Stations (RLS) (e.g. more than four for 23…85 A systems or more than six for 110…1200 A systems). The Expansion Modules are available in 4- or 10-port configurations. This allows up to four RLSs for a 4-port and ten RLSs for a 10-port module. An example would be adding a 4-port expansion module to a 23A ElectroGuard. This then allows up to seven RLSs to connect to the system.

Expansion Modules may be ordered with an adjustable time-delay feature (1…30 seconds) in order to allow time for the machine operator to shut down drives or other equipment that requires a controlled stop after a RLS handle has been turned to the OFF position. Consult your Rockwell Automation sales office or Allen­Bradley distributor for other time settings. Enclosed Expansion Modules are available with optional Flex modules to provide status communication to a remote PLC. Communication can be via ethernet, ControlNet, DeviceNet, Profibus or Remote I/O.

NOTE: The status communication option allows a remote PLC to receive status signals from the Expansion Module.
