Hi,

Is what I can do pwm with ssr relay card, connected to an I / O card 1019.
And if yes, in wich frequency range max.

For information, in my application, i would to control a valve : 24 V DC, pwm 1000hz max and perhaps a pump, in 24V DC too.

Otherwise, do you know a ssr relay can do that?

Thanks a lot.

No this would not be possible. It is not so much an issue of the relay (you could probably find one that switched fast enough to emulate a 1kHz PWM signal, note that ours do not however) but the 1019 will not be able to control it that fast. The outputs on the 1019 have a max update rate of 125 samples per second.

125 is the input rate. You may be able to toggle an output at ~1000Hz, but this behaviour certainly isn't guaranteed.
