Binary output modules (BOM)

Introduction
The binary output module has 24 independent output relays and is used for trip output or
any signaling purpose.
Design
The binary output module (BOM) has 24 software supervised output relays. Each pair of
relays have a common power source input to the contacts, see figure 299. This should be
considered when connecting the wiring to the connection terminal on the back of the IED.
The high closing and carrying current capability allows connection directly to breaker trip
and closing coils. If breaking capability is required to manage fail of the breaker auxiliary
contacts normally breaking the trip coil current, a parallel reinforcement is required.
For configuration of the output signals, refer to section
SMBO".
