*1: For dual-redundant pressure clamp terminal block, please do not use STA4D-£0 S1.
*2: When selecting SAI143-£6£or -£F£, you can not choose the option code of pressure clamp terminal block and MIL cable connector.
*3: When using this module in a dual-redundant configuration, order an additional module with the same specifications but without option codes.
*4: When SAI143-£6£or -£F£is selected, you can choose the option code for prevention pin of false insertion.
A mechanismto prevent wrong type I/O module insertion is supported with signal cable. The signal cable used with this I/O module must have option code /SAI143.
*5: Suffix code for “With ISA StandardG3 and high-density installation” is available in case of SAI143-H£C. This is not available in case of SAI143-S.
