NORIS RG51 Limit-Value Switch A59751 Rev F

NORIS RG51 Limit-Value Switch for Frequency | A59751 Revision F

The NORIS RG51 Limit-Value Switch (A59751, Revision F) is a high-precision frequency monitoring module designed to meet the stringent requirements of marine and industrial automation. This instrument, part of the famous Series 5 signal processing line, monitors electrically measured variables and activates an integrated relay when your chosen frequency threshold is reached. Whether it’s monitoring engine speeds on a commercial vessel or controlling motion control in a factory, the RG51 is a reliable option. Its small, flame-retardant enclosure and galvanic isolation enable stable performance even in areas with high vibration or electromagnetic interference.

The NORIS RG51 is an important part of safety and control. It changes frequency input signals, which are generally from speed sensors, into a command to switch. The “Revision F” updates make sure that the software works with newer PLCs and automate controller platforms. It has a drum scale that is easy to use for changing limit values and is protected by an anti-tamper seal to keep people from making modifications in the field.

Main features:

1) Adjustable Threshold: A tamper-proof drum scale is used to set accurate limit values across the input range.

2) Galvanic separation: Complete separation of the input, output, and supply voltages provides signal integrity and equipment safety.

3) Marine-Grade Durability: Built with a flame-inhibiting, self-extinguishing body that can withstand tough maritime circumstances.

4) Visual Diagnostics: The integrated LED indicators show real-time status of power and relay switching situations.
