6.1 Outputs

6.1.1 Trip Relays T1 and T2
The EAFR-110 relay has integrated trip relays T1 and T2 for
tripping the circuit-breakers. T1 and T2 relays are normally
open type (NO).
6.1.2 Trip Relays T3 and T4
The T3 relay output will act as an electronic lock-out relay.
The T3 electronic lock-out relay is normally closed type (NC)
and will hold its position until the manual reset command
or until the auxiliary power supply is lost. When re-applying
the auxiliary power supply, the electronic lock-out relay will
return to the contact condition prior loosing the auxiliary
power. The NC relay T3 can be used for tripping contactor
controlled devices.
The T3 relay follows the operation of T1 and activates when-
ever T1 is activated.
Trip relay T4 is a common trip relay that operates anytime
the T1 or T2 relays operate and can be used either for trip-
ping one more disconnecting device or for a trip alarm for
local or remote monitoring and alarming system. T4 is a
normally open type (NO) relay.
6.1.3 High Speed Outputs (HSO1 and HSO2)
The EAFR-110 contains two high speed semiconductor
outputs: HSO1 and HSO2. These outputs may be utilized
either for direct tripping of a circuit breaker or as heavy
duty signaling outputs. Due to the high current carrying
capacity, HSO1 and HSO2 are capable of supplying current
or light information to a maximum of 20 EAFR-100 series
units without a need for signal amplifiers. HSO1 operation
is dependent on the configuration select dipswitches. For
details see Section 3.6.

6.1.4 Binary Output BO1

One binary output is available (+24 Vdc). The binary out-
put function can be configured using the dipswitches (see
Section 3.5: Dipswitch Settings).
The binary output is polarity sensitive (see Section 7:
N otee:
Wiring Diagram).
6.1.5 System Failure Relay SF
The system failure relay (SF) is a form C type (NO/NC) and
is energized in the healthy condition. Whenever the EAFR-
110 detects a system error or disconnection of the auxiliary
power supply, the contact changes its state. The state of
the SF relay remains the same until the relay returns to a
healthy condition and the SF relay is energized again.
