Terminal Strip
The SG-Link® OEM has an 8-pin wiring terminal strip incorporated on one edge of the
circuit board. This terminal strip accommodates the differential input channel sensor
connection, the single ended connection, and an external power connection.

Pin Number Pin Name Pin Description
1 Vxc
3.0 volt sensor excitation.
2 S+
Positive input to the differential amplifier.
3 S-
Negative input to the differential amplifier.
4 GND
Signal ground (common with pin 7).
5 Sense
Input for three wire mode on quarter bridge strain
gauges. Leave unconnected for full and half bridge
strain gauge applications.
6 Ain
Analog 0-3.0 volt input.
7 GND
Input power ground (common with pin 4).
8 Vinput
Input power positive (3.2-9 volts DC). This circuit is
common with the barrel connector on the enclosure
sidewall. This circuit can be used in place of the external
power supply.

The SG-Link® OEM starter kit is shipped with a Phoenix-brand terminal block connector
to facilitate making lead connections with the Terminal Strip. The terminal block can be
easily soldered into the terminal strip to provide screw-type terminals. Specifications for
the terminal block may be found at:
