Interface system with central power supply and ATEX approval RNx2x DIN rail interfaces

Application The RN22 signal barrier covers a variety of possible applications. Since its signal input can be connected passively as well as actively, it can be used both as an ac tive barrier and passive barrier. The device is available in a single-channel or two-channel version. In the two-channel version, the device can also be used as a signal doubler. The RN22 signal barrier 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 behaves accordingly. HART signals are also transmitted by the RN22. Operators can access the HART signal without loop interrup tion via two lugs on the analog input. RN22 can be used in SIL applications up to SIL2 SC3. The RLN22 NAMUR isolating amplifier is for the safe transmission of 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 an installed width of 12.5 mm. The function of the device is easily con- figurable via DIP switches, with LEDs showing the switching states. With the RNO22 output isolating amplifier, valves or displays can be controlled. The device is also suitable for use in Ex zones. The signal is detected via the passive input and actively forwarded to the valve or display. An intrinsi cally safe variant is also available as an option. Its compact design accommodates one or two channels on 12.5 mm. The RNF22 infeed and alarm module is designed to power the DIN rail system when a 24 V power source is present in the control cabinet. It monitors the voltage, can switch between redundant power supplies and issues an alarm in the event of a fault. At a glance • Low wiring requirements thanks to a central power supply • Save time and costs with a universally usable system with five different functional components • Reliable thanks to the option for a redundant power supply

RNx2x

The RNB22 power supply can power the system when there is no 24 VDC source available in the control cabinet. An RNB22 can supply power for up to 40 modules. A redundant power supply can be set up with two devices. Advantages • One system with five functions • Compact design • Single- or two-channel devices • Central supply via the DIN rail • Active/passive output (RN22) • HART communication without opening the current loop (RN22)
