Data centers circulate massive amounts of cooling water to maintain server rooms at optimal operating temperatures. While the Building Automation System (BAS) typically manages the primary pumps, a redundant safeguard is often essential to ensure uninterrupted water circulation in the event of a control system failure.
For these and other mission-critical applications, the ¼ DIN 531 Hot PID Backup Station provides a reliable secondary layer of protection. Specifically designed to serve as the backup master on critical loops, the 531 continuously monitors the 4–20mA signal passing through to the final control element during normal operation. Should the primary PID pump controller fail, the 531 immediately assumes PID control, ensuring continuous pump operation. At the same time, it transmits a notification to the primary controller or other watchdog systems, alerting facility operations that the backup has engaged.
The 531 is equipped with a bright vacuum fluorescent display, featuring a large five-digit upper readout along with two nine-character alphanumeric lines for clear, at-a-glance status updates.
Key Attributes:
- Easy to configure
- HOT PID Backup station
- Large display with local indication of PV and CV-Nema 4X case with UL Approval
