Products AI/AO HART intrinsic safety barrier KCD2-SCS-EX2 Pepperl+Fuchs signal conditioner

Pepperl+Fuchs has just released the new KCD2-SCS-EX2, said to be the first 2-channel, dual-function AI/AO intrinsic safety barrier in a compact 12.5 mm housing.

The two channels of the KCD2-SCS series interface modules can be configured individually for analog input or analog output control signals.

Units are also HART compatible and can function as output drivers for SMART valve positioners or as a power supply for SMART 2-wire transmitters.

For analog input signals, the control side can be operated either as a current source or current sink via selectable DIP switches on the front panel.

The KCD2-SCS-EX2 is an intrinsic safety barrier that can be used for hazardous area applications (approved to ATEX, IECEx, and UL).

A version for non-Ex signal conditioning in safe area applications is also available. For each version, there is an option of screw terminals or spring terminals with push-in connection technology.

The modules are also suitable for applications up to SIL 2 (SC3) according to IEC61508 ed2 (TÜV Rheinland).
