SAI143-S33 Yokogawa Analog I/O Modules

Description:

Current Input Module
This module inputs 4 to 20 mA signals from the field.
The SAI143 can be made dual redundant

FEATURES
• High performance and low power consumption modular controller
• Memory with ECC.
• FCN-RTU can be used wide temperature range and high altitude place.
• Analog and digital I/Os adequate for gas/oil wellhead control built in CPU module
• Four serial ports for plural communications built in CPU module
• Up to eight additional I/O modules (with NFBU200)
• Wide voltage range (10 to 30 VDC input) power supply module (NFPW426)
• Power supply module can be duplexed (NFBU200 with NFPW444)
• Low heat dissipation eliminates the need for a fan
• A wealth of RAS features — CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more
• Additional I/O modules (except CPU embedded I/Os) hot-swappable
