Rail-mounting universal supply saves panel space
Only 22.5mm wide, the new rail-mounting Mini-PS power supply from Phoenix Contact offers big savings in valuable panel space.
Depending on the type of operation chosen, the user can adjust the high phase of the period, the duration of the period or the frequency.
PWM, frequency-output and single-shot operations are supported, as well as pulse/direction signal output.
Typical applications for pulsewidth modulation include the control of heating elements.
The period duration can be adjusted between 100us and 10s.
The starting phase can be set to 8bit resolution.
The frequency output is similar to the PWM operation, with the only difference that a frequency between 0 and 50kHz is specified.
In single-shot mode an impulse is put out that can be adjusted between 10ęs and 25.5s.
This impulse signal could be used, for example, to control a valve in a filling process.
The volume to be filled would then be proportionate to the impulse duration.
Using pulse/direction signal output the terminal can be used to control stepping motors.
In this process the impulse frequency can be changed continuously between 0 and 25kHz.
The generated impulses are counted by the terminal in a position counter depending on the direction signal upward or downward.
Furthermore a target position can be entered, which causes the impulse output to stop automatically when it has been reached.
