The repeater power supply and input isolation amplifier MCR-Ex-SL RPSSI-2I from Phoenix Contact can be used to supply two logic units with 0/4-20 mA analogue signals from a hazardous zone. Two-wire measuring transducers are supplied with energy and four-wire devices as well as mA current sources can be connected via the non-supplying input with analogue measured value transferred from the hazardous zone via two electrically isolated active outputs.
This repeater power supply saves space in the control cabinet as a result of its narrow design. The patented circuit concept ensures precise transfer behaviour with low power losses, which allows a high service life to be achieved as a result of the low intrinsic temperature rise. Pluggable and coded terminals, either using screw or fast connection technology PIT, allow the devices to be reliably connected in a service-friendly fashion. The mounting rail connector allows the 24 V supply voltage to be bridged for redundancy, which simplifies wiring and allows for system expansion.
The MACX analogue Ex family is certified according to ATEX and IECEx standards for Ex-i circuits for hazardous zones 0 (gas) and 20 (dust) and for installation in hazardous zone 2. The family also includes versions that are not intrinsically safe, SIL-certified according to IEC 61508 to be used in safety-relevant applications up to SIL2.
