Description
Ways to govern the inputs from the software:
- Direct entries where the state willíis the current status.
- Latched inputs, a high status is read when there has been a high status since the last reading, regardless of the time elapsed or the status of the input at the time of reading.
- Inputs as counter. Each of the inputs has a 32-bit counter associated with it, which is incremented automatically. áThe frequency of the rising edge is measured every time it passes from low state to high state (rising edges). The minimum frequency áThe maximum counting rate is 1 KHz. Counting is always in an upward direction.
- Entries as frequencyímeter. Each of the entrances is equipped with a frequency ímeter capable of measuring frequencies from 0 to 255 Hz with an accuracy of 1 Hz.
AlsoéIt is also possible to configure from the software to which corresponds a high or low status, i.e., if the high status is when there is voltage, it is possible to set a high or low status, i.e., if the high status is when there is voltage.óis when there is no voltage or when there is no voltage.
The optocoupler used in the inputs is the SHARP PC354N to which a 2K2 resistor is placed in series with the input diodes. The isolation indicated by the manufacturer is 3750 Volts.
The tensionóThe power supply voltageóThe recommended power supply voltage of this equipment is 24V, but it works correctly with voltages between 9VDC and 30VDC.
