Yokogawa AAI543-H00/K4A00 Analog Output Module (4 to 20 mA, 16-channel, Isolated)

Current Output Module (Isolated)

This module provides 16 outputs of 4 – 20 mA signal. It can be used in a dual-redundant configuration .

Technical Specifications

• Model:
  • AAI543-£5£/-£E£
  • AAI543-£6£/-£F£
• Number of Output Channels:
  • 16, isolated, standard switch-over response in redundant configuration
  • 16, isolated, fast switch-over response in redundant configuration
• Output Signal:4 to 20 mA
• Withstanding Voltage:output and system: 1500 V AC, for 1 minute
• Allowable Load Resistance:0 to 750 Ω
• Circuit-Open Detection:Less than 0.65 mA
• Accuracy:±48 µA
• Data Update Period:10 ms
• Drift Due to Ambient Temperature Change:±16 µA/10˚C
• Maximum Current Consumption:
  • 230 mA (5 V DC)
  • 540 mA (24 V DC)
• Weight:0.4 kg
• External Communication:
  • Pressure clamp terminal
  • MIL connector cable
  • Dedicated cable (KS1)
• HART Communication:Available

HART communication Available 

• A dual-redundant configuration is enabled by using two identical modules with the same suffix codes.
• When AAI543-£6£/-£F£ is installed in a node unit that conforms to the temperature environment, use it in the ambient temperature within the 0 to 60ºC range.
• When a switch-over from control to standby module takes place in the dual-redundant configuration, the maximum period of time when the field output falls below 4 mA is 100 ms for AAI543-£5£/-£E£ (standard switch-over response) and 2 ms for AAI543-£6£/-£F£ (fast switch-over response). In case of connecting fast response type field devices, use AAI543-£6£/-£F£ (fast switch-over response) in the dual-redundant configuration.
• When the dedicated cable is used, the withstanding voltage is 500 V AC (between the input signal and the system). When the ML connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
• When this module is installed in an ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
