Technical specification3.10 Inputs and OutputsTypes of connectionThe following types of connection are available:- “Screw terminals” on the I/O units.- Serial interface for distributed I/O units.- Air and signal connections to upper arm.For more detailed information, see Chapter 4: Specification of Variants and Options.I/O unitsSeveral I/O units can be used. The following table shows the physical number of signalsthat can be used on each unit.DigitalAnalogType of unitOption no.In Out VoltageintputVoltageoutputCurrentoutputPower supplyDigital I/O 24 VDC 20x 16 16 Internal/External 1Digital I/O 120 VAC 25x 16 16 Internal/ExternalAnalog I/O 22x 4 3 1 InternalAD Combi I/O 23x 16 16 2 Internal/External 1Relay I/O 26x 16 16 Internal/External 1Remote I/OAllen Bradley281 128 2128InterBus-S Slave 284-285 64 2 64Profibus DP Slave 286-287 128 2 128Simulated I/O 3Encoder interfaceunit 4Standard 100 100 30 30288-289 11. The digital signals are supplied in groups, each group having 8 inputs or outputs.2. To calculate the number of logical signals, add 2 staturs signals for RIO unit and 1 for Interbus-Sand Profibus DP.3. A simulated I/O unit can be used to form cross connections and logical conditions withoutphysical wiring. No. of signals are to be configured.4. Dedicated for Conveyor Tracking only.Distributed I/OThe total number of logical signals is 512 (inputs or outputs, group I/O, analog anddigital including field buses).Max. total no of units* 20 (including one SIM unit)Max. total cable length 100 mCable type (not included) According to DeviceNet specification release 1.2Data rate (fixed)500 Kbit/s* Max. four units can be mounted inside the cabinet.Product Specification IRB 1400 M98/BaseWare OS 3.1 37
