ANALOG PC BOARD
P/N 45833-0016
The analog Output Interface provides a switch selectable range of current or DC voltage to a peripheral device.
The output from this Fiber Link is software selectable to be proportional to the displayed weight, gross weight
or net weight.
CUTOFF PC BOARD
P/N 45836-0013
The Fiber-Link Cutoff interface provides multiple, low current logic controlled outputs for switching external devices on or
off at pre programmed or operator selected levels.
This Fiber-Link is also capable of supporting communication to the Analog Fiber-Link via connector P1. However,
both Fiber-Links will require independent power sources.
Connectors:
U1 Fiber Optic receiving port.
P1 Provides the output signal from the Cutoff Fiber-Link to the Analog Fiber-Link via a 2-wire cable when both
Fiber-Link options are required in an installation.
P2 Connector for 18 VAC wall-mount transformer (W-T P/N 45035-0038). The Cutoff Board changes the 18VAC
Into 28 VDC which is capable of supplying up to 167mA of current for the operation of relay coils. The 28 VDC is
also regulated to +5 VDC to power the board.
Note: If the number of relays to be operated will exceed the 167 mA of current, an external DC power source
will be needed. See Connector J21 for more information.
P3 Not used.
P4 Pins 1 and 2 are shorted together to allow the board to receive data from U1.
J21 Relay coil connection. When an external power source is required, connect the minus(-) side of the DC power
source to J21, pin 37 and the +12 VDC to +28 VDC power source to J21, pins 24 and 33.
