YOKOGAWA SAI143-H33 Analog input module Large inventory

The Yokogawa SAI143-H33 is a discontinued analog input module for the ProSafe-RS distributed control system (DCS). It was designed to accept 4 to 20 mA current signals from field devices such as temperature sensors, pressure transmitters, and flow meters. The SAI143-H33 could be used in single or dual redundant configurations.

The SAI143-H33 has been replaced by the newer SAI143-H63 module. The SAI143-H63 has a wider input range (0 to 20 mA or -10 to +10 V) and higher accuracy than the SAI143-H33.

Here are some of the specifications of the Yokogawa SAI143-H33:

• Number of input channels: 16
• Input range: 4 to 20 mA
• Accuracy: ±0.1%
• Resolution: 12 bits
• Isolation: 250 V AC
• Power supply: 24 V DC
