The extended warranty is subject to specific conditions. For full details, please refer to the locally applicable General Terms and Conditions (GTC), which can be found on the respective country page of our website.
The RLN22 is a compact 1- or 2-channel, 24 VDC isolating amplifier with relay signal output. It is designed to safely operate e.g. proximity sensors or point level switches such as the Liquiphant FTL51B (NAMUR) as per IEC 60947-5-6. The DC interface monitors line faults such as breaks or short-circuits of sensors or mechanical switching contacts. The device is suited for use in hazardous areas and safety instrumented systems up to SIL 2 in accordance with IEC 61508.
Isolating amplifier for the galvanically isolated transmission of binary switching signals, also suitable for use in hazardous areas (Ex zone 2)
Input for proximity sensors according to NAMUR (IEC 60947-5-6) and for contacts with or without resistor circuits
Optionally available with resistive coupling element for cable monitoring of mechanical switching contacts
Monitoring of the input circuits for line faults such as breakage and short-circuit (LFD), can be disabled
Benefits
Safe and reliable switching operations for confidence in critical applications
Up to SIL 2 (SC 3) in accordance with IEC 61508 for high functional safety
Compact housing width: up to 2 channels in just 12.5 mm (0.49 in) for efficient use of space in the control cabinet
Quick and easy wiring using screw or push-in terminals
Optional power supply and error message via DIN rail bus connector
Output-side relay contacts as signal outputs; direction of action (operating current behavior or closed circuit current behavior) can be selected via DIP switches
Group error message from the connected isolating amplifiers via DIN rail bus connector to the power supply and error message module
Setting up and monitoring equipment at an ammonia plant presents significant challenges. Engie Energía uses advanced technological solutions, like remote communication devices in hazardous areas.
