23 / 121 page  B7A/B7AS B7A/B7AS 21 Operation Power Supply There are normal-speed and high-speed 16-point models, which are different in recommended transmission cable and transmission distance. If only a single power supply is connected to either the input model or output model, the current on the power line will be limited. Screw Terminal Models I/O Delay: Normal Speed Connection of Independent Power Supplies IN SIG SIG – (–) + (+) SIG SIG – (–) + (+) OUT ERR ERROR Transmission distance 500 m max. SIG – Note: A VCTF cable with a thickness of 0.75 mm2 min. must be used for signal transmission. +– DC power supply (12 to 24 V) +– DC power supply (12 to 24 V) B7A/B7AS B7A/B7AS Connection of Single Power Supply to Input or Output Terminal SIG SIG – (–) + (+) SIG SIG – (–) + (+) ERR ERROR – + IN OUT Note: In this example, a VCTF transmission cable with a thickness of 0.75 mm2 is used, through which a current of 1.8 A max. can be transmitted. +– DC power supply (24 V) SIG Transmission distance 100 m max.

It is recommended that the shield be grounded. The maximum transmission distance is 10 m if a VCTF wire with a thickness of 0.75 mm2 is used instead of a shielded cable for the trans- mission path. +– DC power supply (12 to 24 V) (12 to 24 V) Transmission distance 100 m max.
