What SAI143-H63/PRP is built to handle
SAI143-H63/PRP is a Yokogawa FIO analog input module for 16 isolated 4–20 mA input channels. The H variant adds HART communication, allowing compatible HART field devices to communicate through the input architecture while the analog input function remains available to the control system. The suffix combination is important
The complete code should be considered during replacement. -H identifies HART communication, 6 specifies the signal cable interface adapter without explosion protection, 3 specifies ISA Standard G3 with a -20 to 70 °C temperature specification, while /PRP adds the prevention pin for false insertion. Dual-redundant capability
The SAI143 family can be used in a dual-redundant configuration. When a dual-redundant configuration is required, the additional module is ordered with the same specifications but without option codes. |

16 CH
Isolated 4–20 mA Inputs
Sixteen analog input channels with module isolation support the standard 4–20 mA signal range. |
HART
Field Device Communication
One HART device can be connected per channel, with each channel providing a power supply function to the HART device. |
/PRP
False-Insertion Prevention
The prevention pin works with the matching SAI143 signal-cable arrangement to help prevent incorrect module insertion. |

|
One HART device per channel
Each channel can connect to one HART device and provides a power supply function to the HART device. |
|
|
SAI143-S
Standard 4–20 mA analog input family without the HART communication selection. |
SAI143-H
HART-capable 4–20 mA analog input family with 16 isolated channels. |
SAI143-H6□
HART version with signal cable interface adapter and no explosion protection when the sixth suffix position is 6. |
SAI143-H63/PRP
HART + signal cable interface + ISA Standard G3 / -20 to 70 °C + false-insertion prevention pin. |
Several SAI143 configurations share the same 16-channel 4–20 mA foundation, but their communication, connection, environmental and insertion-protection selections are different. For a replacement project, matching the complete suffix is therefore more useful than matching the base model alone.
|
1. Confirm the communication requirement
If HART communication with field devices is required, the H variant is relevant. The module supports one HART device connection per channel, while only one HART device can be communicated with concurrently by the module. |
2. Confirm the field connection
SAI143-H63/PRP uses the signal cable interface adapter. It is not interchangeable by assumption with SAI143 variants intended for pressure clamp terminals or MIL cable connections. |
|
3. Confirm the environmental configuration
The third suffix selection specifies ISA Standard G3 and an operating temperature specification of -20 to 70 °C. |
4. Confirm the anti-mismatch mechanism
/PRP adds a prevention pin for false insertion. The corresponding signal cable must use the /SAI143 option when this prevention mechanism is used. |
