Do you want to run the I/O modules of the Odot C series not right next to the PLC, but distributed at the machine or in a sub-distribution? Then put a bus coupler in front of them. It connects up to 32 C-series modules via the fieldbus of your controller, whether your PLC comes from Siemens, Beckhoff, Kinco, Odot or another manufacturer. You just choose the coupler with the matching fieldbus.
🏭 Typical applications
Distributed I/O at the machine: sensors and actuators are wired on site, only one network or bus cable runs to the PLC.
Expanding existing plants: if a Siemens or Beckhoff controller is short of channels, you add them via PROFINET, EtherCAT or PROFIBUS without replacing the PLC.
Together with the Odot C4374: the C4374 is a master for Modbus TCP, Modbus RTU, EtherCAT and CANopen. The matching couplers are CN-8031, CN-8011, CN-8033 and CN-8021. This lets you build additional I/O stations controlled by the PLC.
Building automation and control systems: with BACnet/IP or Modbus TCP the modules deliver their data directly to BMS or SCADA systems.
🌐 Available fieldbuses
Modbus RTU (CN-8011) · PROFIBUS DP (CN-8012) · CANopen (CN-8021) · DeviceNet (CN-8022) · Modbus TCP (CN-8031) · PROFINET with MRP (CN-8032) · PROFINET without MRP (CN-8032-L) · EtherCAT (CN-8033) · EtherNet/IP (CN-8034) · POWERLINK (CN-8035) · BACnet/IP (CN-8038). The Ethernet versions have 2 RJ45 ports (10/100 Mbit/s) for daisy-chaining in line topology.
💡 Device description files: the matching GSD, GSDML, EDS or XDD files for integration into your PLC software are in the Downloads tab of each coupler. You configure the I/O modules with the free Odot software IO-Config.
🔧 Technical data (all couplers)
Expansion: up to 32 I/O modules of the Odot C series per coupler
Supply: system and field supply 24 V DC, galvanically isolated, with reverse polarity protection; field current max. 8 A
Environment: operation −35 °C to +70 °C for horizontal, −35 °C to +60 °C for vertical mounting; storage −40 °C to +85 °C; protection class IP20
Mounting: 35 mm DIN rail, push-in terminals, dimensions 51.5 × 115 × 75 mm (W × H × D), 130 g
⚠️ Don't forget the end module: every station needs an end module CT-5801 at its end. It is not included with the bus coupler, please order it as well.
🏷️ Manufacturer
Odot Automation (Sichuan Odot Automation System Co., Ltd.) specialises in IEC 61131-3 controllers and distributed I/O systems. The bus couplers are part of the C-series system and work with all digital, analog, temperature and special modules of the series.
