- The ES40 and ES20 signal converters simplify the management of the control logic and of the supply circuits for the electrovalve, transforming the output signal on the PLC into a voltage value not influenced by the supply voltage fluctuations, suitable for controlling a proportional hydraulic bidirectional valve.
- ES40
- The converter transforms the 6-bit binary value applied on the digital inputs into a voltage suitable for controlling a proportional hydraulic bidirectional valve.
Using the regulation trimmers it is possible to set the operative range accurately. -
- Power supply voltage Vdc. 24 (+/- 25%)
- 6 digital Inputs PNP Vdc. 24 with status led
- Output voltage for electrovalve control,
range 25% - 75% of the Vdc. - Sizes: mm. 100 (h) * 23 (l) * 120 (d)
- ES20
-
- The converter transforms the voltage (0-10 V range) on the inputs into an output voltage suitable for controlling a proportional hydraulic bidirectional valve.
The safety circuit checks the input voltage, activating the error output and bringing the output back to 50% of the supply voltage in case of anomalies. An enable input and two emergency inputs for manual operations complete the control logic. -
