■ 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).
■ Configuration
Table 3-14 ： Configuration device
■ Specifications
1) Up to eight stations can be connected to this unit. (One station occupies one unit.)
One unit is built into the controller as a standard, so up to seven units can be installed as expansions.
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.
The detailed specifications of the input/output circuit are the same as the parallel input/output unit mounted as a
standard. Refer to
Page 58, "3.9 Parallel input/output unit"
for details.
