IXARC ROTARY ENCODERS WITH MODBUS RTU INTERFACE

modbusnewspage2020

Cost Efficient and Reliable Measurement

Position and motion sensor specialist POSITAL has announced that it has expanded its range of absolute rotary encoders and inclinometers to include support the popular Modbus RTU communications interface.

Modbus RTU is a low-cost, easy-to-implement communications protocol that is commonly used in small to mid-sized control systems (up to 32 nodes). Available for almost four decades, it is supported by many PLC manufacturers and has been used in a wide range of applications, ranging from solar panel positioning to controls for packaging systems and mobile machinery. The Modbus RTU protocol makes use of RS485 transmission standard with unshielded twisted-pair cabling. This combination can communicate reliably over distances of up to 1,200 metres, even in the presence of electromagnetic interference (EMI).

  • Low-cost, Easy to Implement Communication System
  • Magnetic Multiturn Sensing without Gear or Battery
  • Programmable Measurement Resolution, Zero Setting and Direction
  • Well Established & Supported by most PLC Manufacturers
  • Available in a Wide Range of Mechanical Configurations

POSITAL IXARC Encoders With Modbus RTU

POSITAL IXARC encoders with Modbus RTU interfaces are available in a wide range of mechanical configurations. Customers can select exactly what they need in terms of the housing material and level of environmental protection, shaft type and diameter, mounting flange and connector type. Customers can also choose between single- and multi-turn measurement ranges. For multi-turn models, the rotation counter is powered by energy harvested from the rotation of the device’s shaft, eliminating the need for backup batteries and reducing maintenance costs.
