2.8 Logic Alarm Cable Connection and Functions
This section describes how to connect the digital input/alarm output terminals.
WARNING
Make sure the signal source is OFF while connecting the wires to avoid electric shock.
CAUTION
• Fix the signal wires to the back of the mounting panel. Pulling the input/output signal wires with
strong force may damage terminals and signal wires.
• Use wires that resist rated temperature 70°C or higher to avoid fire hazards.
• Do not apply voltage that exceeds the following to input terminals. Applying high voltage may
damage the device.
Digital signal terminal : max + 24 VDC
Alarm output relay terminal : 250 VAC/2A, 30 VDC/2A
Caution on Connecting Cables
Follow the directions below when connecting the digital input/alarm output wires.
• Use crimp terminals with insulating sleeves (for 4 mm screws) when connecting signal wire to a terminal.
• Connect the protective ground terminal. Resistance to ground must be 50Ω or less.
Connecting Cables
(1) Remove the terminal cover.
To remove the cover, pull the cover in direction B
while applying force in direction A.
(2) Connect the signal wire to the input terminal.
Recommended screw torque is 12 to 14 kgf/cm.
Refer to the following figure to connect wires to terminals.
(3) Place the terminal cover back on.
