Dear customers,do you need high quality P+F KFD2-SOT3-EX1.LB Switch Amplifier,we can offer a discount offer for you.

P+F KFD2-SOT3-EX1.LB product description:

1-channel isolated barrier

24 V DC supply (Power Rail)

Dry contact or NAMUR inputs

Passive transistor output, non-polarized

Passive fault output, non-polarized

Line fault detection (LFD)

Reversible mode of operation

Up to SIL 2 (SC 3) acc. to IEC/EN 61508

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 passive 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 a fault indication output.

A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
