CAN communication interface. In addition, Eltorque actuators support Digital
and Analog connections.
Figure 3 shows Eltorque actuators connected to a cabinet with an Eltorque
valve control system (E-VCS). In this example, pump starters are also
connected to the E-VCS. Other equipment, such as sensors, can also be
connected to the E-VCS. The E-VCS includes an HMI interface on the cabinet
and can also support an HMI interface on the main control level.

Figure 4 shows Eltorque actuators connected directly to customer-specific
PLC, PC, or other control units. In addition, Eltorque actuators support digital
and analog connections. At a system level, the PLC, PC or Controller must be
compliant with Eltorque communication protocol according to Eltorque
System Integrators Manual CANopen Interface.
