Digital outputs
Notice | |
Feedback at the 24 V outputs A voltage of 24 V at the outputs can destroy the device if the power supply (Up) is not connected (feedback). Connect the power supply (Up) so that 24 V can be applied to the outputs. |
The digital outputs forward binary 24 V DC control signals, electrically isolated, to actuators at the process level. The high level of the positive switching logic corresponds to the supply voltage.
Outputs 3 and 4 have a PWM output stage. If the two digital outputs are used as normal digital outputs, the internal wiring will cause a leakage current of less than 100 µA, which will cause a voltage of about 5 V. If you want to reach nearly 0 V at the low level of the output, you have to connect a 47 kΩ resistance to ground.
Another possibility is to operate the two outputs in PWM mode and to write the variable PWM output of the PWM signal for FALSE with 0x0000 and for TRUE with 0xFFFF. This activates the PWM output stage, which does not generate any leakage current.
The CX7000 contains a total of four outputs, which indicate their signal state by means of light emitting diodes. The outputs can be used to switch standard actuators such as contactors and valves.
