1. What products are involved in this article?

This article is based on the use of the SME (Smart Module Electronics) from SRV, SRD, DVP, and DVM. It highlights the use of a UPS to stabilize the 24V DC power supply, ensuring reliable sensor performance. While a UPS is beneficial for power stability, it is not required for normal operation.

2. What is the purpose of this article?

This article guides using Smart Module Electronics (SME) with Rheonics sensors—SRV, SRD, DVP, and DVM. It highlights the use of UPS to stabilize the 24V DC power supply, ensuring reliable sensor performance.

3. What is a din rail industrial ups?

A DIN rail industrial UPS (Uninterruptible Power Supply) is a backup power device specifically designed to provide stable, continuous power to industrial systems in the event of a power interruption. Mounted on a standard DIN rail, this type of UPS is built to support critical equipment, such as control panels, instrumentation, networking, and automation systems in industrial environments. 


Key points when selecting a DIN rail industrial UPS:


4 . Reliable Power Protection for Industrial Applications

  1. Ensures uninterrupted power and backup for critical systems, including control and instrumentation equipment.
  2. Built to support demanding industrial environments like factories, warehouses, and edge computing locations.
  3. Protects sensitive control and instrumentation from power fluctuations, ensuring stable and precise operations.
  4. Offers extendable backup runtime with optional battery modules, maintaining service during power disruptions.

5. Minimizes Downtime During Power Outages

  1. Offers runtime to keep operations active during brief power losses and allows for safe shutdown during extended outages, protecting both data and equipment.
  2. Shields systems from brownouts, surges, overvoltages, and line noise, preserving the integrity of control and instrumentation systems and reducing costly downtime.

6. Why is it Important?

In industrial environments, even brief power interruptions can halt operations, damage equipment, and cause costly downtime. A DIN rail industrial UPS provides backup power, allowing for safe shutdowns and protecting productivity and equipment during power disturbances.

7. How to size an Industrial UPS to protect the Rheonics SME?

Proper UPS sizing is crucial to ensure that connected equipment receives stable, uninterrupted power during outages and voltage fluctuations. If a UPS is undersized, it may fail to provide adequate power, leading to unexpected shutdowns, data loss, and potential damage to sensitive devices.

  1. Voltage Compatibility: Ensure UPS provides stable 24V DC within the device’s 18-36V range.
  2. Power Requirements: Choose a UPS with at least 5W to cover the device’s 3W max power need.
  3. Current Requirements: Select a UPS that supplies at least 200 mA for reliable operation.
  4. Battery Runtime: Choose sufficient battery capacity for a desired backup time.
  5. Final UPS Selection: Pick a rugged, DIN-rail UPS that meets voltage, power, and runtime requirements.
