ERI1809-0022 | BECKHOFF | Boîtier IO-Link

Description

Directly capturing 16 digital sensor signals from the field, the Beckhoff ERI1809-0022 distributes decentralized I/O data through an integrated IO-Link interface. Built with a robust zinc die-cast housing, this module offers superior mechanical resilience and shielding compared to standard plastic housings, making it suitable for wet, high-vibration, and demanding industrial environments. The device operates as an IO-Link Class A device, transmitting input states to any compatible IO-Link master via a high-speed COM3 interface.

Features

• 16 Digital Inputs: High-density sensor integration in a single field-mounted block.
• Zinc Die-Cast Housing: Enhanced mechanical protection, impact resistance, and electromagnetic shielding.
• IO-Link COM3 Interface: Supports high-speed data transfer rates up to 230.4 kbaud.
• Adjustable Input Filter: Configurable input filtering from 0 to 20 ms (3 ms default) to prevent signal bounce.
• Type 3 Input Characteristics: Conforms to EN 61131-2 Type 3 standards, optimizing current draw for modern electronic sensors.
• IP67 Rated Protection: Fully sealed against dust and water immersion, designed for direct machine mounting without an enclosure.

Applications

• Decentralized Conveyor Systems: Distributed sensor gathering across extensive logistics layouts.
• Automotive Assembly Lines: Rugged, weld-spatter-resistant installations requiring high-density digital feedback.
• Packaging Machinery: Compact field wiring to eliminate centralized junction boxes.
• Machine Tooling: Wet environments where coolant and metal chips are present.

Alternative Models & Compatibility

The ERI1809-0022 is the direct zinc die-cast equivalent of the plastic-housed EP1809-0022. Both modules share identical electrical specifications, pin configurations, and firmware registers. If replacing an EP module, the ERI offers identical mount spacing, but features a thicker profile. Ensure adequate depth clearances within your mechanical footprint.

Application Pitfalls & Engineering Notes

Because this is an IO-Link Class A module, both the unit's internal logic and the connected sensor field power are drawn entirely from the primary L+ and L- lines of the IO-Link master port. The total available sensor supply is limited to 0.5 A. Connecting power-hungry inductive sensors or high-current photoeyes can cause the internal short-circuit protection to trip. For configurations exceeding 500 mA, consider utilizing an IO-Link Class B module or an auxiliary power supply distribution block.

Commissioning & Wiring Tips

By default, the digital inputs are configured with a 3.0 ms hardware filter. While effective for typical proximity switches, high-speed applications (such as rotary encoders or flow pulse meters) will require updating the parameter index via the TwinCAT System Manager (or other IO-Link configuration tools) to 0.0 ms. Always utilize shielded M12 cables for runs exceeding 10 meters to prevent high-frequency noise interference from adjacent variable frequency drives.
