(5) Parallel I/O unit
■ Order type: 2A-RZ361(Sink type)
2A-RZ371(Source type)
■ Outline
This is used to expand the external inputs and outputs. One one equal with this unit
is built into the control unit among controllers the standard.
・ The connection cable is not included. .Prepare the optional external input/output
cable (2A-CBL05 or 2A-CBL15).
・ Use 2A-RZ361 if the external input/output signal logic is of the sink type and 2A-
RZ371 for source type signal logic.
Notes) Although the combined use with the parallel I/O interface (2D-TZ368) of another option is also possible,
please use the setup of the station number by the different number separately. The station number is automati
-
cally fixed by the position of the option slot which installed the parallel I/O interface in 0-2.
■ Configuration
Table 3-22 ： Configuration device
■ Specifications
1) The parallel I/O interface (2D-TZ368) of another option, and the a maximum of eight pieces in all. (One sta
-
tion occupies one unit.)
2) The power supply (24V) must be prepared by the customer and connected with the power connection cable
(DCcable-2)
A separate 24V power supply is required for the input/output circuit wiring.
