YOKOGAWA ALR121-S00 Industrial Serial Communication Module
The YOKOGAWA ALR121-S00 is a robust limit alarm relay designed for industrial control systems. Key specs include a wide operating voltage range of 100-240 VAC, SPDT relay output, and adjustable alarm setpoints. It's typically used in process control for monitoring temperature, pressure, or flow, triggering alarms when limits are exceeded. Compared to the AIP121-S00 and ALP121-S00, the ALR121-S00 offers enhanced reliability and a simpler setup, ideal for applications requiring straightforward limit monitoring without complex programming.
