EQ2100LCU LOCAL CONTROL UNIT
INPUT VOLTAGE—
18 to 30 vdc. 10% overvoltage will not cause damage
to the equipment.
INPUT CURRENT—
EQ2100LCU:
0.4 ampere maximum.
EQ2101LCU:
12 amperes maximum.
OUTPUT CURRENT (EQ2101LCU ONLY)—
System:
2.8 amperes maximum
(ground fault monitored)
1.8 amperes standby current
2.8 amperes alarm current
Auxiliary:
8.0 amperes maximum
(input power to LIOU auxiliary).
RELAY OUTPUT RATING—
5 amperes resistive at 30 vdc.
I/O PORTS—
The LCU provides two electrically isolated RS-232 serial
ports, port “1” and port “2,” both of which can be active
simultaneously. Port “1” can be configured as either a
Modbus RTU slave, or an Allen Bradley DF1 slave. Port
“2” can be either a Modbus RTU slave or master.
Two 78.5 kb LON/SLC ports provide the start and end of
the communication loop for the detection devices. The
wiring is transformer coupled to protect the
transceivers. The LON/SLC is monitored for ground
faults.
TEMPERATURE RANGE—
Operating:
+32°F to +140°F (0°C to +60°C).
Storage:
–67°F to +185°F (–55°C to +85°C).
HUMIDITY RANGE—
0 to 95% RH, non-condensing.
VIBRATION—
Meets MIL SPEC 810C, method 514.2, curve AW.
DIMENSIONS—
See Figure X-1A for dimensions of the standard LCU
mounting configuration. The LCU can also be housed
in a 19 inch mounting rack (000840-xxx), with any
combination of up to 4 logic controllers, 4 gateways and
one isolation module. See Figure X-1B for dimensions.
