Relay modules: IOX8R and REL485
I/O module IOX8R
Expected availability: November 2025
The digital I/O module IOX8R can be used, for example, for the switching of indicator lights, magnetic valves and load contactors. Due to the fast bus communication, it is ideal for filling stations. The module is designed for installation in a switch cabinet or junction box on a DIN rail. Buttons, switches or sensors can be connected via the isolated digital inputs.
IOX8R:
- 8 digital rely outputs (N/O contacts), 250 V AC / 2 A or 24 V DC / 2 A
- 8 digital inputs: 24 V DC @ 3,75 mA
- Spring-based push-in connection (tool-free)
Diagnostic functionalities:
- Link LEDs
- Power, status, I/O LEDs
Supply voltage: 24 V (18 … 30 V)
Data communication: EtherCAT® Input and output port for RJ45 network cables.
Housing:
- Plastic housing (polycarbonate) with transparent hinged lid
- Dimensions: W x H x D: 162 x 90 x 61 mm
Operating temperature: -10°C to +55°C
Protection class: IP20
Assembly: on 35 mm DIN rail in switch cabinet / junction box; tool-free mounting
Homologaciones:
- EU Declaration of Conformity
- ETL (C/US)
- FCC
Note: EtherCAT® is a registered trademark and patented technology, licensed by Beckhoff Automation GmbH, Germany.

The RS485 relay module is used in combination with a weighing terminal for the input and output of digital signals. Typical applications are switching on/off solenoid valves, pilot lamps and motor control centers. Via the optoisolated inputs, push buttons, switches and sensors can be connected.
RS485:
- 8 relay outputs with galvanic isolation 24 V DC / 2 A or 250 V AC / 2 A
- opto-isolated transistor inputs (24 V / 7 mA)
- Status LEDs for all inputs/outputs for easy commissioning and troubleshooting
Supply voltage: 9-36 V DC
Serial interface: RS485/4
Housing:
- Compact pvc housing for installation on DIN rail, insusceptible to vibration
- Dimension W x H x D: 150 x 52 x 75 mm
Operating temperature: –10°C to + 40°C
Protection class: IP20
Mounting: DIN rail mounting in the control cabinet
