Handling Precautions
• The AI value of an AI block that is not used for control cannot be monitored
using the display or communication. When monitoring is required, set the
loop type so that the relevant block is used for control.
Analog output block (current outputs, CT inputs, and VT inputs)
1: CT input
2: CT/VT common
3: VT input
4: Current output +
5: Current output −
Maximum allowable input
CT: 90 mA and 130 mA peak (AC),
1 V and 1.4 V peak (AC)
VT: 18 V and 26 V peak (AC)
Transient overvoltage
CT: Supply voltage + 250 V
