(12)Analog I/O module
• Install a ferrite core to the external power supply connection cable, keeping a distance of 4cm from the
module.
Ferrite core: ZCAT3035-1330 manufactured by TDK Corporation
4cm
(13)Redundant CPU
Use the QCTR tracking cable, and ground the shield section of the cable to the control panel using the AD75CK
cable clamp (Mitsubishi). For the grounding method, refer to (2).
(14)I/O signal cables and other communication cables
• For I/O signal cables (including common lines) and other communication cables (such as cables for RS-232,
RS-422, and CC-Link), ground the shield sections (in the same way as explained in (1)) when the cables are
extended out of the control panel.
• To set the input response time of the input module and the interrupt module to 0.1ms or less, keep the each
cable length of I/O signal cables (including common lines) to 30m or shorter.
(15)Extension cables
For extension cables, ground the shield sections (in the same way as explained in (1)) when the cables are
extended out of the control panel.
