Description Model AAI841 Analog I/O Module (4 to 20 mA input , 4 to 20 mA output, 8-channel input/8-channel output, Non-Isolated) -S Standard type -H With digital communication (HART protocol) Suffix Codes 0 Always 0 0 Basic type 3 With ISA Standard G3 option and temperature (-20 to 70 _C) option /K4A00 With KS Cable Interface Adapter [Model : ATK4A-00] /A4S00 With Pressure Clamp Terminal Block for Analog [Model : ATA4S-00] Option Codes /A4S10 With Pressure Clamp Terminal Block for Analog (surge absorber) [Model : ATA4S-10] /A4D00 With Dual Pressure Clamp Terminal Block for Analog [Model : ATA4D-00] /A4D10 With Dual Pressure Clamp Terminal Block for Analog (surge absorber) [Model : ATA4D-10] /CCC01 With Connector Cover for MIL Cable [Model : ACCC01] *1: This module does not allow a Zener barrier to be connected. If the module is to be used in intrinsically safe applications, use an isolation barrier. *2: Viewed from the terminals, module input resistance is, depending on the current flowing: voltage drop in the input protection circuit 250 Ω + current value F07E.ai *3: When installing to a remote node that conforms to the temperature environment and using it under the temperature environment (60 to 70 ˚C), the allowable load resistance is 200 to 750 Ω. *4: This voltage is developed between connecting terminals for this module’s 2-wire transmitter. When calculating if transmitter minimum operating voltage requirement will be satisfied, remember to allow for voltage drop in external wiring. *5: The module current output does not allow a Zener barrier to be connected. If the module is to be used in intrinsically safe applications, use an isolation barrier. *6: This module current input does not allow a Zener barrier to be connected. If the module is to be used in intrinsically safe applications, use an isolation barrier. *7: R4.03 or later version supports this module. This module must be used with following FCS. AFG30 £, AFG40 £ , AFG8 ££, AFF50£ , or AFV10 £ . *8: Input mode of each channel is selectable by software. *9: When installing the module with HART function to a remote node, the firmware of EB401 must be Rev 2 or later.
