Description
This device has been designed to vary the pulse time of a relay with a 0-10 V signal. The pulse frequency (10, 5, 2, 1 0.5, 0.1 Hz) is fixed on the device with a button. The 0-10 V input signal control the time on wich the relay stay at the on state (see figure). The frequency can be visualised on a display.
For exemple if the input signal is 0 V and the frequency 0.5 Hz, the output stays low. If the input signal is 10 V, the signal stays high. If the input signal is 5 V, the output stays 1 second low and 1 second high.
Typical applications
- control of on/off valves
- automation (pressure control with a valve)
