(2). Connecting the Signal Lines
• Separately procure the relay, power supply for the relay, terminal block, and cable locally.
• The maximum wire length is 100 m (328 ft). However, since the use of long wires makes the device susceptible to noise, using wires
shorter than 10 m (32.8 ft) is recommended.
• Connect another relay within 10 m (32.8 ft) from DIDO controller to extend the input line.
1) Standard Terminals (Channels 1 and 2)
(1-1) Input
(a) Non-voltage a-contact Inputs
NOTE
• Connect the operate/stop (ON/OFF) inputs so that closing the contact operates (ON) the device and opening
the contact stops (OFF) the device.
• The error/normal inputs of channels 1 and 2 can be switched between a-contact and b-contact.
CAUTION
• The polarity of the input terminals is important, so be sure to match the polarity when using contacts that have
polarity.
• Select a contact with a minimum applicable load of 1 mADC or less.
• Supply 24 VDC 1 mA from the positive terminal to the external contacts.
• Do not install alongside or in contact with other wires.
• 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.
