P&F Barrier -

KCD2-SR-Ex2.SP - Switch Amplifier

Used for:

• This is an isolated barrier is used for intrinsic safety applications.
• The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area.
• useful for detecting positions, end stops, and switching states.
• The device output changes the state when the input signal changes the state.
