Output characteristics
• The photocoupler is used to insulate the analog input area from the PLC.
Insulation method • The DC/DC converter is used to insulate the power supply from the analog output.
• Channels are not insulated from each other.
Number of I/O points
8 points (Taken from either the input or output points of the PLC.)
occupied
*1. Adjustment of the offset or gain value will not affect the resolution.
*2. The offset and the gain should satisfy the following condition:
1V ≤ (Gain - Offset) ≤ 15V
*3. The offset and the gain should satisfy the following condition:
4mA ≤ (Gain - Offset) ≤ 32mA
