Multiprotocol field-mounting IO-Link master simplifies engineering
9 September 2026 
ifm electronic has announced a decentralised multiprotocol IO-Link master for use in the field. The AL1602 master combines flexible I/O configuration, high output current, and IP67 protection. The multiprotocol interface allows it to be integrated into different fieldbus architectures without changing the hardware, thus supporting standardisation and reducing engineering effort.
The device is part of a new generation of decentralised IO-Link masters in ifm’s AutomationLine series. It addresses the challenge of reducing engineering effort while maintaining flexibility across different control architectures. By combining communications, power supply and configuration in a field-mounted device, the AL1602 helps to standardise machine designs and reduce the number of variants needed.
It provides eight IO-Link ports supporting class A and B, with 16 freely configurable digital inputs and outputs. The channels can be configured and operated flexibly to match the application. A current rating of up to 2A per output makes the master suitable for direct control of motorised rollers, conveyor drives, diverters and stoppers.
A common ground concept enables compact, cost-efficient designs, while a daisy-chain function simplifies voltage supply to multiple masters and reduces wiring effort.
