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.
