2.1 Performance Specifications
The following table lists the performance specifications of the RJ51AW12AL.
*1 For remote modules with transmission cables (DP, DN), the length of the transmission cables (DP, DN) is included in the total wiring
length.
For wiring of 50m or more with 4 wires (DP, DN, 24V, 0V), insert the noise filter for power supply cables between the power supply and
cables. For details, refer to the manual for the AnyWireFILTER (ANF-01) manufactured by Anywire Corporation.
*2 For the relation of the total wiring length, wire diameter of transmission cables (DP, DN), and transmission cable supply current, refer to
the following.
On some remote modules with cables, the wire diameter of module-integrated transmission cables (DP, DN) may be smaller than
0.75. However, they can be used without any problem, provided that the wire diameter of transmission cables (DP, DN) meets the
following requirements.
*3 When the operating ambient temperature is 50 or higher, use cables with a temperature rating 75 or higher.
*4 The performance specification differs depending on the production information of the RJ51AW12AL. ( MELSEC iQ-R
