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 296.
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
outputs SMBO".
