The Pepperl+Fuchs KFD2-SOT2-EX1.LB (part no. 181002) is a single-channel switch amplifier from the K-System range, used in marine control systems as an isolated barrier between field switching devices and the control electronics. It accepts dry contact or NAMUR inputs and passes the state on through a passive, non-polarized transistor output, with a separate passive fault output and line fault detection. The mode of operation is reversible, it is rated up to SIL 2 according to IEC/EN 61508, and it takes a 24 V DC power-rail supply of 20-30 V at no more than 50 mA. It is in used condition.
Key Features
✓ 1-channel isolated barrier
✓ Dry contact or NAMUR inputs
✓ Passive non-polarized transistor output and passive fault output
✓ Line fault detection (LFD) with reversible mode of operation
✓ Up to SIL 2 according to IEC/EN 61508
Marine Applications
✓ Bringing NAMUR proximity sensor signals into ship automation PLCs
✓ Isolating dry contact inputs from valve position switches
✓ Line-monitored switch inputs for engine room alarm and monitoring systems
✓ Safety-related shutdown circuits rated up to SIL 2
Technical Support
Prota Marine provides technical support, repair and onboard installation for the switch amplifier and the wider marine control system. Our engineers assist with fault diagnosis on the amplifier, its field inputs and its outputs, and provide commissioning support on the power rail.
