The very popular Siemens 353 SLC controller was discontinued, leaving many process users high and dry for a suitable replacement. We're glad to announce that there is a great alternative - the Yokogawa YS1700 PID loop controller.
The YS1700 is a drop-in SLC replacement for the Siemens 353 and is an ideal choice for many control applications offering extreme reliability and sophisticated control. This product family has bright, easy-to-read displays, multiple I/O points, and powerful loop tuning. For critical applications, the YS1700 employs dual CPUs for maximum reliability and hard-manual control for added protection.
