5.2 Module connection example
The figure below shows an example of voltage input and current input
connections.
*1: Use a 2-pole twist shielded wire.
*2: Represents the input resistors of the A1S68AD. (For voltage input,
turn off the 250 resistor with the Input range selector switch.)
*3: If the external wiring causes noise or ripple, connect a capacitor of
0.1 to 0.47 F (25V or more voltage resistance parts) between the V
and COM terminals.
(2) Current input
Signal source:0 to +20mA
(1) Voltage input connection
Signal source 0 to 10V
