2–4 Hardware Features
Publication 2755-6.13
The interface box routes signals between the readers and an external
package detect. The interface box has the following components:
•
Power transformer. Supplies a stepped down and isolated voltage
that produces the 12V dc power for the interface box and external
sensor.
•
F2 control fuse holder. Contains the 12V dc fuse for the interface
box.
•
F1 triac fuse holder. Contains the fuse for the triac output.
•
Power terminal block. Provides the input connection point for the
AC line that supplies power to the interface box.
•
Triac terminal block. Provides the output connection point for
the reader–controlled power output.
•
LED status indicators. Provides the status of power supply,
package detect, and sensor alarm circuits.
•
Voltage selector switch. Allows you to configure the interface
box to match the incoming line voltage.
•
J1 jumper. Allows you to configure the sensor input.
•
J2 jumper. Allows you to configure the sensor input alarm.
•
Package detect terminal block. Provides the connection point for
the package detect.
!
ATTENTION: Before applying power to the interface
box, make sure the voltage selector switch is in the
correct position.
