(2) Channel 1 (Channel 2) Analog Input (4 to 20 mADC, 1 to 5 VDC, 0 to 10 VDC)
To use these, various settings need to be configured.
Refer to "8 Initial Setting Procedure".
7-4. Connecting Upper/Lower Limit Alarm Outputs (Non-voltage Contacts)
The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to noise, using wires
no more than 10 m long is recommended.
To use these, various settings need to be configured. Refer to "8 Initial Setting Procedure".

Caution:
• Select a power supply that is suitable for the sensor to be used.
• Do not install the sensor input line parallel to or near the M-NET 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.

Caution:
• To use X1 relay, obtain one that satisfies the following
specifications.

MAX: 24 VDC, 5 W (Built-in diode)
MIN: 5 VDC, 2 mW (Built-in diode)
*1 AC loads cannot be connected.
*2 Provide a power supply (V1, V2) that matches the load
and relay to be used.
• To drive a direct load, use ones within the following.

• 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.
• Do not connect the wires directly from the top of the control
panel to the terminal block.
Moisture may enter this device along the wiring and cause
electric shock or fire.
Tightening torque for terminal screws: 1 N·m.
* The contact of the internal relay is always ON during
detection of an upper/lower limit alarm. (Level output)
