Please use the cable of 0.5mm [AWG20] or more.
The cable must fit into TB530 and meet DC12V power supply.
Notes
• Connecting terminal TB530 for power supply is polarized, so confirm proper polarity of the terminals before connecting.
• Do not connect DC12V from the DC power supply to TB571.
• Confirm polarity when using a diode built-in relay. C of TB571 is electropositive potential
● For TB571 and TB530, insert wiring after inserting the flathead screwdriver into the terminal.
● Appropriate electric wire for TB571 and TB530 is as follows. Stranded wire: 0.3mm
[ø1/64in. to ø3/64in.]
● Peeling dimension of the electric wire for TB571 and TB530 is 7mm to 10mm [9/32in. to 25/64in.].
● Wiring length from the interface to Relay 1 and Relay 2 should be less than 50m [164ft].
