Product Description
The Yokogawa SAI143-S33 is a 16-channel analog input module that receives 4-20 mA current signals from field transmitters for processing by a control system. It provides module-level isolation and supports an input range of 0-25 mA. The module also specifies a 40 ms data update frequency and a transmitter power supply function, with 2-wire and 4-wire settings configurable for individual channels.

Input Signals and Channel Configuration
The module accepts standard 4-20 mA transmitter signals and permits input currents up to 25 mA. The 16 input channels use module isolation. Individual 2-wire or 4-wire settings allow the wiring configuration to be selected for each channel, while the transmitter power supply ON/OFF function in 2-wire mode operates across all 16 channels simultaneously.
Transmitter Power Supply
The transmitter supply specification gives a minimum voltage of 16.15 V DC at 20 mA and a maximum of 26.4 V DC at 0 mA, with an output current limit of 25 mA. These conditions are relevant when checking the supply voltage available to a connected transmitter under load.
Frequently Asked Questions
Q: How many analog input channels does the SAI143-S33 provide?
A: It provides 16 input channels with module isolation. The rated signal range is 4-20 mA, with a permissible input range of 0-25 mA.
Q: Can the module support both 2-wire and 4-wire transmitters?
A: The specifications list individual 2-wire and 4-wire settings selected by setting pins. The transmitter power supply ON/OFF function is available in 2-wire mode and applies to all 16 channels simultaneously.
Q: What is the difference between the SAI143-S and SAI143-H accuracy specifications?
A: Both variants specify +/- 16 uA accuracy, but their stated input ranges differ. The SAI143-S range is 1-23 mA, while the SAI143-H range is 0.05-23 mA. The supplied information does not establish which accuracy designation applies specifically to the SAI143-S33 suffix.
