2.3 Performance Specifications
*1. Adjustment of the offset or gain value will not affect the resolution. In the direct indication mode, however, the
offset/gain cannot be adjusted.
*2. The offset and the gain should satisfy the following condition:
1V ≤ (Gain - Offset)
*3. The offset and the gain should satisfy the following condition:
3 mA ≤ (Gain - Offset) ≤ 30 mA
*4. The resolution and the input/output characteristics depend on the selected mode.

±0.3% (±60mV) for full scale of 20V
• Ambient temperature: 0°C±55°C
±0.5% (±100mV) for full scale of 20V
• Ambient temperature: 25°C±5°C
±0.5% (±200µA) for full scale of 40mA
Same (±200µA) when input is 4mA to 20mA
• Ambient temperature: 0°C±55°C
±1% (±400µA) for full scale of 40mA
Same (±400µA) when input is 4mA to 20mA
Time required for
A/D conversion
500µs × number of selected channels
(If 1 or more channels use the digital filter(s): 5ms × number of selected channels)
Insulation method
• The photo-coupler is used to insulate the analog input area from the PLC.
• The DC/DC converter is used to insulate the analog input area from the power supply unit.
• Channels are not insulated from each other.
Number of I/O
occupied points
8 points (Count either the input or output points of the PLC.)
