The NAMUR isolating amplifier is designed for safe operation of proximity switches according to EN 60947-5-6 (NAMUR) as well as open and mechanical contacts with resistive coupling elements. It has a universal power supply (24 to 230 V AC/DC) and one relay output (changeover) per channel. The device is approved for intrinsically safe (Ex i) circuits up to zone 0 (gas) and zone 20 (dust) in the Ex area. RLN42 can be used in safety equipment up to SIL 2 in accordance with IEC 61508.
Isolating amplifier for the galvanically isolated transmission of binary switching signals, also for use in hazardous areas (Zone 2/Div. 2)
Wide-range power supply from 19.2 to 253 VAC/DC
Input for proximity sensors according to NAMUR (IEC 60947-5-6) and for potential-free contacts or contacts with resistance circuits
Optionally available with resistive coupling element for cable monitoring of mechanical switching contacts
장점
Quick and easy wiring using screw or push-in terminals
Up to SIL 2 in accordance with IEC 61508 for high functional safety
Compact housing: 17.5 mm (0.69 in) for efficient use of space in control cabinets
Output-side relay contacts as signal output; direction of action can be selected via DIP switches
For ambient temperatures –40 to 60 °C (–40 to 140 °F)
Monitoring of the input circuits for line faults such as line break and short-circuit (LFD), disengageable
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.
