Figure 6: Connection harness (with CANopen connector)
In older versions of the QT50 the connections must be done directly on the
connection board. This is described in version 1.9 of this manual, (document ID
1321 v. 1.9).
The QT50 can be delivered with the following interfaces.

CANopen – interface using the CAN (Controller Area Network)
communications standard. Eltorque recommends a maximum of 80 nodes on
500 m / 1660 ft. cable.

Digital – interface allowing simple Open & Close operation of valves.
Actuators with Digital Interface can be controlled directly from a conventional
panel with buttons/switches and indicator lamps. Alternatively, it can be
controlled from a PLC with digital inputs and outputs.

Analog – interface allowing regulating valves where positioning of the valve
is needed. The actuator provides continuous feedback of its actual position,
for comparison between desired and actual position.
Note! The QT50 does not provide a Modbus interface. If a Modbus interface is required,
please contact your Eltorque representative to find a solution.
More technical details on the different communication interfaces is given in
Chapter 7 Technical Details on page 51.
