Specification of Variants and Options
62 Product Specification IRB 4400 M98A/BaseWare OS 3.2
CABINET I/O MODULES
201-208 Digital 24 VDC I/O: 16 inputs/16 outputs.
221-228 Analog I/O: 4 inputs/4 outputs.
231-238 AD Combi I/O: 16 digital inputs/16 digital outputs and 2 analog outputs (0-10V).
251-258 Digital 120 VAC I/O 16 inputs/16 outputs.
261-268 Digital I/O with relay outputs: 16 inputs/16 outputs.
Relay outputs to be used when more current or voltage is required from the digital
outputs. The inputs are not separated by relays.
Connection of I/O:
301 Internal connection (options 201-204, 221-224, 231-234, 251-254, 261-264)
The signals are connected directly to screw terminals on the I/O units in the upper part
of the cabinet (see Figure 41).
305 External connection
Standard industrial connectors, 64-pin/socket plugs in accordance with DIN 43652,
located on the left-hand side of the cabinet. Corresponding cable connectors are also
supplied.
FIELD BUSES MOUNTED IN CABINET

281 Allen-Bradley Remote I/O Slave
Up to 128 digital inputs and 128 digital outputs, in groups of 32, can be transferred
serially to a PLC equipped with an Allen-Bradley 1771 RIO node adapter. The unit
reduces the number of I/O units that can be mounted in cabinet by one. The field bus
cables are connected directly to the screw terminals on the A-B RIO unit in the upper
part of the cabinet (see Figure 41).
284/285
InterBus-S Slave
Up to 64 digital inputs and 64 digital outputs per unit, in groups of 16, can be
transferred serially to a PLC equipped with an InterBus-S interface. The unit reduces
the number of I/O units that can be mounted in cabinet by one. The signals are
connected directly to the InterBus-S-slave unit (two 9-pole D-sub) in the upper part of
the cabinet, and to a 5-pole screw connector.
286/287
Profibus DP Slave
Up to 128 digital inputs and 128 digital outputs per unit, in groups of 16, can be
transferred serially to a PLC equipped with a Profibus DP interface. The unit reduces
the number of I/O units that can be mounted in cabinet by one. The signals are
connected directly to the Profibus DP slave unit (one 9-pole D-sub) in the upper part
of the cabinet, and to a 5-pole screw connector.
