Cable requirements and recommendations
EMC glands are not mandatory but are recommended in
case the actuator is placed in conjunction with
equipment emitting high levels of disturbance.
Nominal 120 Ω Both ends of the signal loop must have
the correct impedance. See chapter 4.8.2 for Single
CANopen interface connection or 4.8.3 for Dual CANopen
interface connection.

Cable requirements and recommendations
Cable length
With Hybrid Marine
Cable
Maximum 500 m/1650 ft.
For other cable lengths and number of nodes contact your local
Eltorque representative and we will help you to get the correct set-
up.
For Hybrid Marine cable nominal 120 Ω.
Both Dual CAN inputs on the actuator must be impedance matched
to the characteristic impedance of the cable used. When projected
by Eltorque, this is handled by our project personnel.
For the analog interfaces, both the input and the outputs are passive. Analog
has two outputs. One Alarm output and one Position output (4 to 20 mA)
(see Table 6 for details).
Table 6: Relay outputs – analog interfaces
Limiting continuous current
For the digital interfaces, the digital outputs are passive, and the digital
inputs are active with a 5 V/20 mA rating. The digital output must be
powered (see Table 7 for details).
