Curtiss-Wright Implements PROFINET IO Communications on Tritex II 

Chanhassen, MN—April 8, 2014—Curtiss-Wright Corporation (NYSE:CW) today announced that its Exlar business units will implement the PROFINET IO with its Tritex II actuators. PROFINET is the Ethernet based automation standard of PROFIBUS International. The Tritex II integrated actuator line has passed the PROFINET IO Conformance testing performed by the PROFI Interface Center.  

This communication link to your PLC will enable you to send and receive the data you need in a timely manner to operate the Tritex II actuator with your machine automation control system. Some of the highlights of the Exlar PROFINET IO implementation:

  • Transfer of up to 100 input and 100 output words
  • PROFINET register mapping and configuration setup through the Tritex Expert software interface allows access to any parameter
  • Connection through industrial standard M12 Ethernet connector
  • Connectivity to Siemens PLC models that support PROFINET IO

The Tritex II actuators are offered in 100-240VAC or 12-48VDC allowing direct connection to factory power sources. Expert software features include 16 programmable indexes, linked moves and communications via the actuator’s Modbus port. This port via RS/485 protocol allows complete control, programming and monitoring of all aspects of the Tritex actuator as it performs an application.

The Tritex actuator has ample I/O capability: eight digital inputs, four digital outputs plus one analog input and output. The new Tritex design offers excellent connectivity with internal terminals accessible through the actuator’s removable cover. Tritex also offers provision for Imperial or metric threaded ports for cable sealing glands, optional M23/M16 connectors for power and I/O, with an M8 connector for the RS485 port.

Tritex linear actuators provide the same form factor as hydraulic and pneumatic actuators, and provide for simple and clean all-electric retrofits in what were formerly fluid power applications. They are available with many different mountings (metric or imperial) such as front flange, rear clevis mount, side mount, trunnion mount, extended tie rod and rear flange.

Tritex rotary actuators are available in standard IEC metric dimensions. Direct drive units as well as units with integral planetary gearing provide compact powerful solutions for most rotary applications. Custom mounting and options for both rotary and linear actuators are available to meet all of your installation requirements.
