SIL 3-certified signal conditioners


Phoenix Contact’s MACX Analog now includes input-loop-powered passive conditioners

MIDDLETOWN, Pa. − Phoenix Contact introduces new 0(4)-20 mA isolators with up to SIL 3 functional safety data. The latest additions to the MACX Analog family are two-way, input-loop-powered isolators.

The devices allow operation on active sensor technology with a supply voltage of 6 V to 30 V DC. They are powered via the sensor’s current loop, so they do not require an additional power supply. The single- and two-channel variants are available with two levels of isolation at 2.5 kV or the HV version at 5 kV. They feature plug-in connection technology for quick installation.
