PHD-22TF-2828

Supply voltage

20~35VDC, power consumption<1.0W

Input signal

Switch contact/proximity switch

Supply voltage from sensor side on site

8V

Signal input characteristics

On-site input current: >2.1mA, it means ON; On-site input current: <1.2mA, it means OFF  Switch hysteresis: 0.2ms

Transistor output characteristics

NPN type transistor emitter or collector open circuit output, drive capacity: output current ≤20mA (1.2KΩ), internal maximum current 100mA. Equipped with short-circuit current protection

Switched control between inverted phase and normal phase of outputs e-c

When the dial switch K1 is at "ON", the transistor output e-c are in inverted phase

When the dial switch K1 is at "OFF", the transistor output e-c are in normal phase

When the K2 is at  "ON", the circut will select the red light indication alarm function

Indicating light alarm function

Field input current >7mA, short-circuit alarm (SC), on-site input current < 0.1mA, open-circuit alarm (LB). Switch contact input, when disconnection detection function is required, a 10kΩ resistor should be connected in parallel at both ends of the switch (Please see the switch contact II in the wiring diagram below).
