Modbus RTU

New ultra-compact Modbus RTU I/O Modules

Modbus RTU Series
  • Freely scalable up to 247 units in one Modbus segment
  • Extremely slim, only 6.2 mm installation width
  • Easy configurable via DIP switches or USB interface
  • Highest accuracy and temperature stability
  • Protective galvanic separation between all circuits, test voltage 3 kV AC
  • In-Rail-Bus Connector for Power and Modbus
  • Protection against overvoltage, polarity error and short circuit at all terminals
  • Long service life, extremely low failure rate due to reduced self-heating
  • Made in Germany, 5 Years Warranty

The DRAGO Modbus RTU I/O Modules combine complex field and control requirements such as protective galvanic isolation, maximum signal integrity and highest reliability with fast measurement data conversion and field bus provision.

Up to 4 fully isolated I/Os are available in the 6.2 mm slim modules. The configuration can be made via DIP switch or USB interface. In addition to standard signals, mA, V, mV, R, Pot, Hz, PWM and all current industrial sensors can be processed.

Power supply and bus connections are pre-wired on standard DIN rail by the In-Rail-Bus. All terminals are protected against short circuit, overvoltage and polarity reversal. The protective galvanic isolation with 3 kV test voltage permits working voltages up to 300 V. A low bus load allows up to 247 modules (988 I/Os) in one Modbus segment.

The low-power design ensures minimum self-heating for a wide temperature range. The high separation quality and short response time guarantee an economic integration in new plants and retrofit projects.
