Yokogawa SAI143-H53 S2 16-Channel Analog Input Module 12-Month Warranty

FAQ

What is the main application of the SAI143-H53 S2 module?
The module is primarily used to input 4–20 mA analog signals from field devices in process automation systems and transmit accurate data to the ProSafe-RS system.

Can the SAI143-H53 S2 module be used in a dual-redundant configuration?
Yes, the module supports dual redundancy, but an additional module with the same specifications is required without option codes for dual-redundant setup.

What is the effect of ambient temperature on the module performance?
For SAI143-S ≤3 or SAI143-H ≤C at temperatures above 60°C, the number of usable channels may be restricted. Refer to the ProSafe-RS module guide for details.

How is the transmitter power supplied and controlled?
The module provides a 16.15–26.4 V power supply with a 25 mA current limit. In 2-wire settings, power to all channels can be switched ON/OFF simultaneously to reset alarms of Fire and Gas devices.

What are the HART communication capabilities of this module?
Each channel supports one HART device. The module uses serial half-duplex communication with a speed of 1200 bps and FSK modulation.

What is the rated accuracy and input range?
Rated accuracy is ±16 µA for input ranges of 1–23 mA. Style code S3 or later supports 0.05–23 mA with the same accuracy.

What types of external connections are supported?
Connections include pressure clamp terminals, MIL cables, and dedicated signal cables, with support for options like prevention pins or connector covers for flat ribbon cables.

What is the weight and size of the module?
The module weighs approximately 0.34 kg and has dimensions of 130 × 107.5 × 32.8 mm.
