Specifications

  • Items: 16, isolated signals
  • Model: AAI143 (*1)
  • Number of input channels: 16, isolated
  • Input signal: 4 to 20 mA
  • Allowable input current: 24 mA
  • Power ON: Between input and system: 1500 V AC, for one minute (*4)
  • Withstanding voltage: 270 Ω (20 mA) to 350 Ω (4 mA) (*2)
  • Input resistance: 500 kΩ or larger
  • Accuracy: ±16 μA
  • Data update period: 10 ms
  • Transmitter power supply: 19.0 V higher (at 20 mA), 25.5 V lower (at 0 mA) (output current limit: 25 mA) (*5)
  • Setting of 2-wire or 4-wire transmitter: For each channel by setting pin
  • Drift due to ambient temperature change: ±16 μA/10 °C
  • Maximum current consumption: 230 mA (5 V DC), 540 mA (24 V DC)
  • Weight: 0.3 kg
  • External communication: Pressure clamp terminal, MIL connector cable, dedicated cable (KS1)
  • HART communication: Available

Notes:

  1. A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in intrinsically safe application.
  2. The module input resistance viewed from the terminals depends on the current strength as calculated below: 250Ω+voltage drop in the input protection circuitcurrent value
  3. When the dedicated cable is installed to a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
  4. When the ML connector connector is used, the withstand voltage is 500 V AC (between the input signal and the system). When the withstand voltage depends on electrical specifications of transmitters.
  5. This voltage is generated between connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider margins for voltage drop in external wiring.
