WIRING
This chapter describes the wiring of the D/A converter module.
6.1

Terminal Block

Precautions
Tighten the module fixing screws and others within the specified torque range.
Screw type
Module fixing screw (M3)
Terminal screw (M3)
Terminal block mounting screw (M3.5)
*1 The hook on the top of the module allows the module to be fixed to a base unit easily. In a place where a vibration occurs frequently,
however, fixing it with module fixing screws is recommended.
The following table lists an applicable solderless terminal to be connected to the terminal block. When wiring, use the
applicable wire and tightening torque in the table. Use UL listed solderless terminals and, for processing, use the tools
recommended by their manufacturer. Note that a solderless terminal with an insulation sleeve cannot be used.

Signal names of the terminal block
The following table shows signal names of the terminal block.
Terminal block
Terminal blocks that have been used on MELSEC-Q series digital-analog converter modules can be used just
the way they are. The terminal layout is the same as the MELSEC-Q series high speed digital-analog
converter modules (Q64DAH).
The terminal blocks for MELSEC-L series digital-analog converter modules, however, cannot be used
because of the shape difference.
