ITV electro-pneumatic regulators convert an electrical command into proportional air pressure. An internal pressure sensor feeds the output pressure back to the control circuit, which operates the air supply valve to follow the selected current or voltage input. ITV1000, ITV2000 and ITV3000 body sizes offer three pressure ranges, digital pressure indication and selectable monitor outputs.
| Body family | 0.005-0.1MPa | 0.005-0.5MPa | 0.005-0.9MPa |
|---|---|---|---|
| ITV1000 | ITV101□ | ITV103□ | ITV105□ |
| ITV2000 | ITV201□ | ITV203□ | ITV205□ |
| ITV3000 | ITV301□ | ITV303□ | ITV305□ |
| Maximum supply pressure | 0.2MPa | 1.0MPa | |
| Minimum supply pressure | Set pressure +0.1MPa | ||
The square in each model represents the selected power-supply code. The minimum controlled output is 0.005MPa; operation below that point is outside the proportional control range.
| Parameter | Option | Specification |
|---|---|---|
| Power supply | 24VDC ±10% | Current consumption ≤0.12A |
| 12-15VDC | Current consumption ≤0.18A | |
| Input signal | Current | 4-20mA DC or 0-20mA DC, sink type |
| Voltage | 0-5VDC or 0-10VDC | |
| Preset input | 4 points, negative common; 16 points, no common polarity | |
| Input impedance | Current input | ≤250Ω |
| Voltage input | Approximately 6.5kΩ | |
| Digital input, 24VDC supply | Approximately 4.7kΩ | |
| Digital input, 12VDC supply | Approximately 2.0kΩ |
Current-input versions require a separate power supply; a two-wire 4-20mA arrangement is not available. The current-input impedance value excludes overcurrent protection allowance; at a 20mA input, the stated limit including this allowance is 350Ω.
| Output | Rating |
|---|---|
| Analog voltage | 1-5VDC; output impedance approximately 1kΩ |
| Analog current | 4-20mA DC, sink type; output impedance ≤250Ω |
| Analog output accuracy | Within ±6% of full span |
| NPN open collector | Maximum 30V, 80mA |
| PNP open collector | Maximum 80mA |
Select either analog monitoring or a switch output; switch versions are configured as NPN or PNP. For the 1-5VDC monitor, a measuring load below 100kΩ may prevent the stated accuracy from being achieved.
| Parameter | Specification |
|---|---|
| Linearity | Within ±1% of full span |
| Hysteresis | ≤0.5% of full span |
| Repeatability | Within ±0.5% of full span |
| Sensitivity | ≤0.2% of full span |
| Temperature characteristic | Within ±0.12% of full span per °C |
| Pressure display accuracy | Within ±2% of full span ±1 digit |
| Display resolution | 0.001MPa; 0.01kgf/cm²; 0.01bar; 0.1psi; 1kPa |
| Ambient and fluid temperature | 0-50°C, no condensation |
| Enclosure | IP65 |
Performance figures apply to static conditions; outlet pressure may fluctuate when air is consumed. The pressure display unit is selected when ordering and cannot be changed. The maximum numerical setting is 0.9MPa, equivalent to approximately 130psi.
