Interface devices with universal power supply unit and ATEX approval for individual applications RN42 and RLN42 DIN rail interfaces

At a glance • Universally usable thanks to universal power supply unit • Two-channel version saves space and money • Safe to use for Ex zone applications and applications up to SIL2 SC3

Application The RN42 barrier offers various possible appli cations. Since its input can be connected passively as well as actively, it can be used both as an active barrier and passive barrier. The device is designed as a single-channel version. The RN42 can be used very flexibly, meaning the output can be connected to passive as well as active PLC inputs. The device detects the type of output and adapts its function accordingly. HART signals are also transmitted by the RN42. Operators can access the HART signal without loop interrup tion via two lugs in the front. The RN42 can be used in SIL applications up to SIL2 SC3. The RLN42 NAMUR isolating amplifier is for safely trans mitting digital states from Ex zones to non-Ex zones. It is suitable for SIL applications up to SIL2 SC3. Its compact design accommodates two channels on a width of 12.5 mm. The function is easily configurable via DIP switches, with LEDs showing the switching states. Advantages • Universal PSU – a single device for all applications • Compact design: 12.5 or 17.5 mm • Passive/active output (automatic detection with RN42) • ATEX approval • For SIL applications up to SIL2 SC3
