Connecting to the Analog Input
The analog input can be used only in SCL mode. The analog input can be read back to the
“Host” using the “IA” immediate type and “RA” buffered type commands. Readings are in
Volts.
+5 volt DC is provided for powering potentiometers. A 1000 to 10000 ohm potentiometer is
recommended and should be connected as shown below.
A 0 to 5 volt analog signal may also be used. Usually this signal comes from a PLC, a PC
with data acquisition card or a motion controller. Connections are shown below.
The +5V terminal is an output. Do not connect it to a power supply.
