Maximum 176 binary input channels may be activated simultaneously
with influencing factors within nominal range.
23.2.8 Binary output modules (BOM)
IP14536-1 v1
23.2.8.1 Introduction
M6938-3 v4
The binary output module has 24 independent output relays and is used for trip output
or any signaling purpose.
23.2.8.2 Design
M1819-3 v4
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
315 . 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 "Signal matrix for binary
outputs SMBO" .
