  • Programmable and modular inputs, supporting multiple input types of thermocouples, RTDs, voltage/current and two-wire transmitters. Suitable for measuring and displaying temperature, pressure, flow, level, humidity, etc with measurement accuracy of 0.2% full scale (0.3% full scale for AI-500).
  • Single display window to set parameters and alarm points. Various dimensions are selectable.
  • Supports up to 4 loops of alarms including 2 loops of high limit alarms plus 2 loops of low limit alarms. Alarms can be outputted to different relays or share one.
  • With functions of digital calibrating, digital filtering, and thermocouple cold junction auto compensating, it is free of maintenance and easy operated.
  • Supports RS485 communication interface, able to communicate with computers.
  • Retransmission function, cooperating with X3 high precision current output module (0.2%FS), can retransmit temperature with accuracy of 0.3%FS.
  • High quality and performance hardware design, using high performance tantalum capacitor or ceramic capacitor. Compared to competing models, it consumes less electricity, experiences less temperature shifting, provides higher stability and reliability and can work in a wider range of temperature. The power and I/O terminals have passed the anti-interference test of 4KV/5KHz burst of pulses.
