Model 10VAC Voltage Input Adaptor

is a special screw-terminal connector assembly which allows the 10A74-4C to receive up to four independent external analog signals in place of its normal strain gage inputs, when it is desired to apply the special TRACK/HOLD function of the 10A74-4C to these analog voltage signals. The analog signal source must provide its own power supply; the Model 10A74-4C’s standard excitation lines cannot be used.
