  Parallel I/O interface   

3 Controller

(2) Parallel I/O interface

■ Order type  ： ● 2D-TZ368 (Sink type)/2D-TZ378 (Source type)

■ Outline

This is used to expand the external inputs and outputs
・ The connecting cable with external equipment is not attached.  Since we are preparing 

the external input-and-output cable (2D-CBL05 or 2D-CBL15) as the option, please use.

Notes)Although the combined use with the parallel input-and-output unit (2A-RZ361/2A-

RZ371) of another option is also possible, please use the setup of the station 
number by the different number separately. The station number is automatically 
determined by the position of the option slot which installed this interface. (station 
number 0 to 1)
