MODULES 
 
POINT 
 
(1) The number of connectable I/O points is 32 for all connector/terminal block 
converter modules.  
Two connector/terminal block converter modules and two cables for 
connector/terminal block converter modules are required for 64-point I/O 
modules. 
(2) Though the A1SX81(S2) is used either as a sink or source type, use the 
A6TBX36-E, A6TBX54-E or A6TBX70-E. 
The A6TBXY36, A6TBXY54 or A6TBX70 cannot be used. 
(3) Though the A1SX82-S1 is used either as a sink or source type, the 
A6TBXY36/XY54/X70 may be used only when the A1SX82-S1 is used as a sink 
type. 
When it is used as a source type, the A6TBXY36/XY54/X70 cannot be used. 
(4) Though the A1SY82 and QY82P are source type output modules, use the 
A6TBXY36 or A6TBXY54. The A6TBY36-E or A6TBY54-E cannot be used. 
(5) In the A series, the positive common input module is separately labeled as a 
sink type input module, and the negative common input module is separately 
labeled as a source type input module. 
(6) When using the A6TBX70 as I/O combined module, use at the input side. 
(7) Tighten the module terminal screws to the following torque. 
Terminal screw (M3.5 screw): Tightening torque 0.78N•m
