With the built-in switch the position PNP N/O 1) or PNP N/C 2) can be chosen. 5) NPN normally closed 6) NPN programmable NPN transistor disconnects the negative supply to output. With the built-in switch the function NPN N/O 4) or NPN N/C 5) can be chosen. Definition of cable colours BN = brown BU = blue BK = black (Output) Sensors Association of the cable colours to the connection pins of the cable couplings see page 276 ff. This association is not valid for all plugs and couplings 1) PNP normally open PNP transistor switches the output high. 4) NPN normally open NPN Transistor switches the output low. 7) PNP/NPN programmable With two built-in switches PNP or NPN and between NO or NC function can be chosen. 8) NAMUR Current change according to DIN EN 60947-5-6. 263 Wiring diagrams of DC output types DC 2-wire DC 4-wire (Principle wiring diagram) (Principle wiring diagram) Key to colour coding of cable BN = BU = BK = WH = brown blue black (switching output) white (switching output) Load for Sinking Load for Sourcing Load for Sinking Load for Sourcing Load for Sinking Load for Sourcing 3) Switch selectable DC 2-wire 1) Normally open DC 2-wire 2) Normally closed DC 2-wire During operation, the contacts are bonded. During operation, the contacts are separated.

Wiring diagrams of AC output types AC 2-wire AC 3-wire (Principle wiring diagram) (Principle wiring diagram) Key to colour coding of cable Load Load 1) Normally open AC 3-wire 2) Normally closed AC 3-wire During operation, a thyristor which is positioned above a rectifier bridge applies the operating voltage to the output. During operation, a thyristor which is positioned above arectifier bridge separates the operating voltage from the output. Load Load 4) Normally open AC 2-wire 5) Normally closed AC 2-wire During operation, a thyristor which is positioned above a rectifier bridge applies the load to the operating voltage.
