ifm CabinetLine IO-Link Masters
AL19xx masters bring IO-Link into the control cabinet with IP20 DIN-rail mounting, removable cage-clamp wiring, eight Class A IO-Link ports and a separate information-system path on current IIoT-capable models.

CabinetLine design intent
Use CabinetLine when the IO-Link master belongs inside the main panel or a remote sub-panel rather than directly on the machine.
02
Class A
Current AL19xx family provides eight standard IO-Link A ports for sensors and standard devices.
03
Independent data path
A separate information-system Ethernet path allows selected sensor data to bypass the PLC application.
04
IO-Link 1.1
Process values, parameters and diagnostics move digitally between devices and the master.
Cabinet architecture
Keep machine control and data collection logically separate
The master exchanges cyclic IO-Link process data with the PLC while selected device information can also be sent to higher-level systems through the separate IoT interface on current variants.

Port boundary: CabinetLine uses A ports. ifm currently documents A-port load current up to 300 mA per port. Applications needing isolated auxiliary actuator power should be reviewed against PerformanceLine or SolutionBlock B-port architectures.
Current CabinetLine routes
Select the controller network first
All four core CabinetLine variants use the same cabinet concept; the fieldbus interface changes by model.
| Model | Controller network | IO-Link | Installation |
|---|---|---|---|
| AL1900 | PROFINET | 8 × Class A ports | IP20 DIN rail / control cabinet |
| AL1920 | EtherNet/IP | 8 × Class A ports | IP20 DIN rail / control cabinet |
| AL1930 | EtherCAT | 8 × Class A ports | IP20 DIN rail / control cabinet |
| AL1940 | Modbus TCP | 8 × Class A ports | IP20 DIN rail / control cabinet |
Model check: current master portfolio and alternative article numbers can change. Confirm the current order-number datasheet before freezing the BOM.
Representative technical data
AL1900 reference point
Use family data for architecture and the selected order-number sheet for final electrical design.
01
20–30 V DC
AL1900 current documentation specifies 20–30 V DC supply and up to 3.6 A total sensor-supply load.
02
16 points
AL1900 documentation lists 8 digital inputs and 8 digital outputs alongside the IO-Link port functionality.
03
Removable terminals
CabinetLine uses removable cabinet terminals rather than M12 field connectors for its IO-Link and supply wiring.
Master alternatives
CabinetLine or another ifm master family?
Choose by mounting location, port power and IIoT requirements.
| Requirement | Review | Reason |
|---|---|---|
| IP20 cabinet / remote sub-panel | CabinetLine AL19xx | DIN-rail architecture and terminal wiring |
| Standard field-mounted IO-Link + IIoT | DataLine AL13xx | IP67/IP69K field format |
| High-current actuators / B ports | PerformanceLine AL14xx | L-coded power and higher-current outputs |
| Multiprotocol + advanced IIoT / OPC UA | SolutionBlock AL15xx | Broader OT/IT functionality |
