(2). Connecting the Sensors
• For channel 1, select one of the following four types: Pt100 detection, 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog input.
• For channel 2, select one of the following three types: 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog input.
• The wire length depends on the specifications of the sensor. However, since the use of long wires makes the device susceptible to
noise, using wires shorter than 12 m (39.4 ft) is recommended. Use a shielded line for the sensor line and connect to the FG terminal
on this unit or the FG terminal on the control panel.
1) Channel 1 Pt100 Input
CAUTION
• Use a 3-wire system for Pt100.
• A/B polarity is important for Pt100.
Be sure to match the polarity when using Pt100.
• Do not install the sensor input line parallel to or near the M-NET transmission line or power line.
Also avoid loop wiring.
Furthermore, confirm the precautions for the sensor.
• Strip 12 1 mm (15/32 1/32 in) of the wire coating and insert firmly into the terminal.
• Make sure that the copper wiring is not short-circuiting the plates (cover, lower case) or neighboring wires.
• Perform wiring so that the terminal block is not strained.
If strained, use a wire guide or junction terminal to alleviate the stress on the terminal block.
