Yokogawa SDV144-S63 Digital Input Module
Technical Specifications:
- Number of channels: 16 channels, which can collect 16 – way digital signals at the same time.
- Input signal type: DC 24V switch signal, with a signal input range of 15-30V DC.
- Response time: 1ms, which can quickly capture the change of the input signal.
- Isolation voltage: 1500V AC, effectively preventing signal interference between channels and ensuring the stability of signal collection.
- Connection method: It adopts a signal cable interface adapter without explosion – proof function, and complies with the ISA standard G3, with a working temperature of -20℃ to 70℃.
- Power consumption: 50mA (5V DC), 150mA (24V DC), with low power consumption and energy – saving characteristics.
Detailed content
- Functional Characteristics:
- The module has isolation design, which can avoid mutual interference between different channels and improve the anti – interference ability of the system.
- It supports channel – by – channel signal detection, and can independently monitor the input status of each channel, which is convenient for troubleshooting.
- The signal latching function can maintain the signal state when the input signal disappears temporarily, ensuring the stability of the system control logic.
- It is compatible with Yokogawa’s CENTUM VP DCS system and can be seamlessly integrated into the system without additional configuration.
- It has a high degree of protection, which can adapt to the harsh industrial environment and ensure long – term stable operation.
- Application Scenarios: It is applicable to the monitoring of the on – off status of various valves and pumps in the petroleum and chemical industry; the collection of limit switch signals of mechanical equipment in the power industry; and the status monitoring of various sensors and actuators in the water treatment industry.
