Analog I/O Terminals Section 4-8
The following table summarizes the DIP switch settings. (All pins are factory-
set to OFF.)
* Factory settings.
Note Always turn OFF the Slave’s power supply (including the communications
power supply) before changing any settings.
Rotary Switch Setting Set the input signal range for each input with the rotary switch. Inputs 0 and 2
share the same signal range, as do inputs 1 and 3.
The voltage input/current input selection is carried out by connecting the V+
terminal to the I+ terminal. Short-circuit the V+ terminal and I+ terminal when
inputting current.
Note Always turn OFF the Slave’s power supply (including the communications
power supply) before changing any settings.
