Introduction:
The AC voltage input signal conditioners are high performance instruments that measure AC voltages in 4 ranges which are as follows: 400 mV, 4 Volt, 40 Volt and 400 Volt. Key features of the signal conditioners are built in active attenuator, scalable analog output and a simple RS232 interface for scaling analog output and range selection. The RS232 interface may also be used for digital transmission of input signal to a computer or a PLC. Additional features include three way isolation between DC power, signal input and analog output/RS232.

Operation:
Note: When connecting a voltage signal, extra care should be taken to prevent electrical shock. Always turn the signal power off before making connections to the signal conditioner.
ALWAYS ENSURE THAT THE MAXIMUM VOLTAGE INPUT SIGNAL DOES NOT EXCEED
400 VOLTS AC.
PLEASE OBSERVE THE INPUT SIGNAL CONNECTION SPECIFIED IN THE SECTION BELOW. THIS DEVICE MUST ONLY BE INSTALLED BY
A PROFESSIONAL ELECTRICIAN.
Power Input and Analog Output Setup:
To connect the signal input proceed as follows:
1.Connect a DC power supply with an output voltage between 10 to 32 Volt DC to the signal conditioner (J1).
Note: If power supply used has current limiting, it may not be able to power the signal conditioners if the available output voltage is around 10 Volt, since the peak current may reach 1 to 5 amp for a few milliseconds.
2.Determine the maximum voltage to be measured.
