MACX MCR-EX-SL-RPSSI-2I(-SP)

Data sheet

1Description

The MACX MCR-EX-SL-RPSSI-2I(-SP) repeater power

supplies and input signal conditioners are designed for the

operation of intrinsically safe 2-wire measuring transducers

and mA current sources installed in hazardous areas.

2-wire measuring transducers are supplied with energy.

4-wire measuring transducers as well as mA current

sources can be operated via the non-feed input.

Analog 0/4 ... 20 mA measured values from the hazardous

area are transferred via two electrically isolated active

outputs to the non-hazardous area.

The analog measuring value can be overlaid with digital

(HART) communication signals on the hazardous or non-

hazardous side and transmitted bidirectionally from both

outputs.

Test sockets are integrated into the connectors for

connecting the HART communicators.

Certified for safety-related applications up to SIL 2

according to IEC/EN 61508.

WARNING: Explosion hazard

The module is an item of associated electrical equipment for intrinsically safe circuits. It is designed for

use in zone 2, if specific conditions are observed.

When installing and operating the device, the applicable safety directives (including national safety directives),

accident prevention regulations, as well as general technical regulations must be observed.

WARNING: Explosion hazard

Observe the safety regulations and installation notes on page 6.

Make sure you always use the latest documentation.
