Technical Specifications​

Power supply: 24 V DC ±20 percent.

Maximum current consumption: 500 mA.

Operating temperature: -25 to 60 °C.

Storage temperature: -40 to 85 °C.

Protection class: IP20.

Dimensions: 119 x 44 x 127 mm width x height x depth.

Functional Features​

Network address setting through DIP switches according to configuration.

Baud-rate configuration for the supported fieldbus.

Node address configuration through software tools.

Bus termination through jumpers according to network position.

Status indication and industrial enclosure for control cabinet use.

Application Scenarios​

PLC I/O expansion, PROFIBUS/PROFINET or general fieldbus integration according to actual firmware, sensor/actuator networking, machine communication panels and retrofit automation systems.

Performance Parameters​

Listed distributor material references PROFIBUS/PROFINET compatibility and baud settings from 9.6 kbps to 12 Mbps for configurable fieldbus nodes; confirm exact protocol by firmware because the model can appear in multiple Helmholz communication families.

24 V DC operation suits standard control-cabinet power.

Material And Structure​

IP20 plastic industrial housing.

DIN-rail clip or cabinet mounting format.

Field terminals, DIP switches, jumpers and status LEDs according to variant.

Removable or fixed connectors depending on actual submodule.

Working Principle​

The module interfaces between the controller backplane or bus and field devices. It processes address, baud and protocol parameters, transfers cyclic I/O data and handles diagnostic status between master and slave nodes.

Installation Requirements​

Mount inside control cabinet with IP20 ambient protection.

Supply regulated 24 V DC with proper fusing.

Set DIP switches or software address before network integration.

Use shielded bus cable and follow Profibus/Profinet or other protocol grounding rules.

Usage Precautions​

Verify firmware and supported protocol before replacing another MDM or bus module.

Do not exceed 24 V DC ±20 percent supply range.

Configure termination only at physical bus ends.

Avoid humidity, condensation and temperatures outside -25 to 60 °C operating range.
