Specifications
General specifications
- Pressures of 0.2 MPa or less cannot be controlled.
- 2-wire type 4 to 20 mA is not available. A power supply voltage (24 VDC) is required.
- Select either analog output or switch output. Further, when switch output is used, select either NPN or PNP output. When measuring analog output of 1 to 5 VDC with a load impedance less than 100 kΩ, the analog output may not achieve the output accuracy of +/- 6% F.S. or less.
- The setting (Zero/Span, Preset input, Switch output) can be adjusted by each minimum display unit. The unit cannot be changed.
- The above characteristics are confined to the static state. When air is consumed on the output side, the pressure may fluctuate.
- This product is not certified by Japan’s High-Pressure Gas Safety Act.
Warning
Special products (-X) might have specifications different from those shown
in this section. Contact SMC for specific drawings.
Installation
Warning
Do not install the product unless the safety instructions have been read
and understood.
- This product is pre-set at the factory and must not be dismantled by the user. Contact your local SMC office for advice.
- Ensure, when installing this product, that it is kept clear of power lines to avoid noise interference.
- Ensure that load surge protection is fitted when inductive loads are present (i.e. solenoid, relay etc.).
- Ensure precautions are in place if the product is used in a ‘free flow output ’condition. Air will continue to flow continuously.
- Ensure all air is exhausted from the product before maintenance.
- The length of the connector cable should be 10 m maximum.
Environment
Warning
- Do not use in an environment where corrosive gases, chemicals, salt water or steam are present.
- Do not use in an explosive atmosphere.
- Do not expose to direct sunlight. Use a suitable protective cover.
- Do not install in a location subject to vibration or impact. Check the product specifications.
- Do not mount in a location exposed to radiant heat.
Piping
Caution
- Before piping makes sure to clean up chips, cutting oil, dust etc.
- When installing piping or fittings, ensure sealant material does not enter inside the port. When using seal tape, leave 1.5 to 2 threads exposed on the end of the pipe/fitting.
- Tighten fittings to the specified tightening torque.
- When connecting piping to a product, refer to its instruction manual to avoid mistakes regarding the supply port, etc. Port 1: Supply port / Port 2: Output port / Port 3: Exhaust port
Lubrication
Caution
- SMC products have been lubricated for life at manufacture, and do not require lubrication in service.
- If a lubricant is to be used in the system, refer to the catalog for details.
- Do not use a lubricator on the supply side of this product, as this can cause malfunction. When lubrication of equipment is necessary, connect a lubricator on the output side of this product.
Wiring
Caution
- Proceed carefully, as incorrect wiring can cause damage.
- Use a DC power supply with sufficient capacity and a low ripple.
- Turn off the power supply to remove and insert the connector.
- Never rotate the right angle connector as it is not designed to rotate.
- Connect the F.G. terminal at the front of the product to the Ground.
Note: The wire colour shown are when the optional cable is used.
Ground connection
Connect the F.G. terminal at the front of the main body to the Ground
(F.G.). If the field ground fluctuates due to noise, it may affect the
operation of the product.
Wiring diagram Current/Voltage type
Preset input type
Note: The wire colours shown are when the optional cable is used.
For safety reasons, it is recommended that one of the preset pressures be set to 0 MPa.
*Analogue output – Voltage type (ITVH2020-1)
**
*Analogue output – Current (Sink) type (ITVH2020-4)
**
*Switch output – NPN type (ITVH2020-2)
** When a current of approx.150 mA or more is applied, the over-current
circuit will operate, “Er.5” will be displayed and the operation will stop.
Install a load to give an output current of 80 mA or less.
*Switch output – PNP type (ITVH2020-3)
** When a current of approx.150 mA or more is applied, the over-current
circuit will operate, “Er.5” will be displayed and the operation will stop.
Install a load to give an output current of 80 mA or less.
Settings
Setting method
Caution
- If an incorrect key is pressed or incorrect information is displayed during setting, power must be turned off and the procedure started again.
- It is recommended that the settings are changed without supply pressure. The product operates immediately maximum and minimum pressures are set and the S-key is pressed.
- It is recommended that the minimum pressure is output when air is supplied to the inlet, even if the input signal has not been entered.
- Output pressure from this product and state of operation are changed by changing of each setting and function.
Key locking function
The keys are locked when power is turned ON and cannot be operated.
Unlocking the keys
Note: Step 4, press △ key to cancel.

The setting of Minimum/Maximum pressure and Switch output
- Note 1) F_1 is adjustable in the range 0 to 90% of the rated value (default value: 0% – 0.00 MPa).
- Note 2) F_2 is adjustable in the range 10 to 120% of the rated value (default value: 100% – 2.00 MPa).
- Note 3) Do not input the signal to output the pressure of more than 100%.
- Note 4) The difference between F_1 and F_2 is adjustable in the range of 10% of the rated value.
- Note 5) The adjustment relationship of F_1 > F_2 is not possible. Note 6) The numbers (2.00 etc.) on the LED display indicate the secondary pressure.
