PWM outputs

6 Installation

Instruction book, IQAN- XT2

PWM outputs

The PWM output (Pulse Width Modulation) control pilot valves. Maximum load
should not exceed 3,0 A per output.

Connecting loads to PWM outputs

The load is connected between the PWMOUT and the chassis ground.
For the maximum load per output, see Appendix A, on page 23.

Protection against voltage transients

A clamping diode must be placed between the output and ground, as close to the load
as possible, to protect the output against high voltages transients.
For example: Use the diode 1N5408 (3A/1000V).
Depending on the load, other clamping diodes might be used instead

EXAMPLE

Positive direction:
Connect the load between the PWMOUT-A, position 2, and the chassis as ground.

Negative direction:

Connent the load between the PWMOUT-B, position 3, and the chassis as ground.

A clamping diode will be placed as close to the pilot valve as possible.
