A new two

June 1, 2023 | By Gerald Ondrey

The new KCD2-SCS-EX2 (photo) is a two-channel, dual-function analog input (AI)/analog output (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. They are also HART compatible and can function as output drivers for smart valve positioners or as a power supply for smart two-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. Each channel is configurable to allow positioner control on one channel (AO), and position monitoring (AI) on the second channel. Positioners ensure that the actuator is brought into a position specified by the control system. — Pepperl+Fuchs Inc., Twinsburg, Ohio
