The actuator offers several digital position output options which can be configured exactly to your requirements. To offer full flexibility, the yellow and green wires can be used for the following outputs:
Digital position feedback as either single Hall or dual Hall. Single Hall does not take direction into account, and this logic must be programmed in the PLC. Dual Hall has two channels – A and B. Both have their own dedicated wire which makes it possible to determine the direction in which the actuator is running.
As either a supplement to the analogue position feedback or a stand-alone feature, you can choose endstop signals that give a signal when the actuator is fully retracted or extended. The same signal will also be applied if virtual limits are set in either direction – indicating that the actuator has reached its new endstop.
It is also possible to receive digital signals from the actuator while running – something that can, for instance, be used to turn on an LED to indicate that something is moving in the application.
In some cases, it might be beneficial to know when the actuator reaches a predefined endstop zone. This feature makes it possible to define a zone where the actuator can send a digital signal when it is inside that zone or at a current limit in that zone. In this way, you are no longer forced to design your application so that the physical endstop must be reached before receiving a PLC (Programmable Logic Controller) signal.
For most of these digital signals, you can choose between an active high or active low signal for easier integration in the application.
If you are looking for a way to power LED or a hand control, you can also choose a constantly high signal. The actuator will supply up to 100 mA to low-power devices directly.
