Triconex 3720

• Triconex 3009 是一款三重冗余控制器，支持符合 IEC 61508 的安全完整性等级 3 (SIL 3)，确保高可靠性和容错能力。
• 它可以在恶劣的环境条件下运行，并具有适合工业环境的特定温度范围。
• 支持各种输入/输出模块，以便与传感器、执行器以及过程控制和安全功能所需的其他现场设备进行接口。
• 配备通信接口，可与分布式控制系统 (DCS)、监控和数据采集 (SCADA) 系统以及其他工厂范围的网络无缝集成。

• Input and Signal Parameters
  • The analog input version has 32 shared points, with a nominal input current of 4 - 20mA DC and an operating current range of 2 - 22mA DC. It has a 16-bit resolution and an accuracy of ±0.01% within the 1000 - 20000Hz frequency range.
  • The pulse input version has 8 high-frequency input points, a pulse count measurement resolution of 1 microsecond, and an input diagnostic fault range of 0.5% of the full scale. The input change sampling cycle is the longer one between one scan and 210 milliseconds.
  • The module has an input bandwidth of 16Hz, an absolute maximum field voltage of 33V DC, and an absolute maximum reverse field voltage of -0.6V DC.
• Power and Electrical Parameters
  • The nominal power supply voltage is 24V DC. The minimum isolation between functional and protective earth is 500V DC, and the minimum isolation between functional and functional earth is 800V DC.
  • The module has a source impedance of 180Ω, an input impedance of 250Ω when paired with a baseplate, and a 100Ω I-to-V resistor with a tolerance of ±0.01%.

• Output and Signal Parameters
  • It has 4 common - return, DC - coupled output channels, with a 12 - bit resolution and an output accuracy of less than 0.25% of the full - scale range within the 4 - 20mA controlled current range.
  • The output current can reach an over - range of 0 - 22mA and also has a 0mA output capability, with a step function response time of less than 2ms.
  • The typical switch time when a channel fails is 1ms, and the maximum switch time does not exceed 3ms.
• Power and Loop Parameters
  • The nominal external loop power supply is 24V DC, and the maximum allowable voltage is 32V DC, with reverse voltage protection.
  • For a 300Ω load, the loop power supply needs to be over 16V DC with a minimum current of 1A; for an 800Ω load, the loop power supply must be over 28V DC with a minimum current of 1A.
  • It has continuous over - range protection against 36V DC and 0V DC, which effectively protects the internal circuitry from damage due to abnormal voltage.
