KFD2-ST3-Ex1.LB Switch Amplifier
●Function
■This isolated barrier is used for intrinsic safety applications.
■The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area. ■The input controls two active transistor outputs.
■Via switches the mode of operation can be reversed and the line fault detection can be switched off.
■Via switch the function of the second output can be defined as a signal output or an error output.
■A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
●Features
■1-channel isolated barrier
■24 V DC supply (Power Rail)
■Dry contact or NAMUR inputs
■2 active transistor outputs
■Usable as signal splitter (1 input and 2 outputs)
■Reversible mode of operation
■Line fault detection (LFD)
■Up to SIL 2 acc. to IEC 61508
