| Part Number: | UF20 | - | RTU | - | EC |
|---|---|---|---|---|---|
| Explanation: |
Platform UF20 - UF20 I/O platform |
Module RTU - Bus coupler; this breakdown covers the three listed UF20 couplers only |
Protocol PN - PROFINET |
UF20 bus couplers connect a local UF20 I/O assembly to an industrial network. Select the PN, EC or MT model for the controller protocol. Each coupler provides two RJ45 connections and supports up to 32 expansion modules; protocol-specific features remain tied to the selected model.
| Characteristic | UF20-RTU-PN | UF20-RTU-EC | UF20-RTU-MT |
|---|---|---|---|
| Protocol | PROFINET | EtherCAT | Modbus TCP/IP |
| Network interfaces | 2 × RJ45 | 2 × RJ45, with switching function | 2 × RJ45 |
| Transmission rate | 10/100Mbps, full duplex | 10/100Mbps, full duplex | 10/100Mbps |
| Address setting | PROFINET specification | EtherCAT specification | Modbus TCP/IP specification; address range 2-253 |
| Coupler supply current | <200mA | <200mA | <150mA |
| Load supply voltage | 24V DC, +20%/-15% | 24V DC, +20%/-15% | 24-32V DC |
| Model | Function | Details |
|---|---|---|
| UF20-RTU-PN | Real-time and network functions | RT; Class C; MRP; automatic addressing and topology detection |
| UF20-RTU-PN | Alarms | Diagnostic, process and connector insertion/removal alarms |
| UF20-RTU-PN | Minimum cycle time | 1ms |
| UF20-RTU-MT | Modbus function codes | 01, 02, 03, 04, 05, 06, 15, 16, 23 |
| Characteristic | All three models |
|---|---|
| Expansion capacity | 32 modules |
| Process data capacity | 1024 bytes |
| Transmission distance | 100m |
| Address mapping | Supported |
| Transmission medium | Category 5 twisted-pair cable |
| Isolation | Electrical isolation |
| Coupler operating voltage | 24V DC, +20%/-15% |
| System supply output | 5V DC; 2A maximum |
| Load supply current | 10A maximum |
Coupler consumption, the 5V system supply and the load supply are separate electrical ratings. In particular, the MT model has a different load-voltage range from the PN and EC versions.
