PPKG-12-30 two-stage deviation switch PPKG-12-30 two-stage deviation switch PPKG-12-30 two-stage deviation switch Scope of application: two-stage deviation switch is used for conventional belt conveyors: underground, cableway support belt conveyors: ship loading and unloading systems; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Crane, excavator, boom limit: skirt feeder/conveyor: heavy-duty limit switch detects the deviation of the tape, which is a protective device for automatic alarm and shutdown of the tape machine control. Widely used in various belt conveyor equipment in fields such as metallurgy, coal, cement and building materials, mining, electricity, ports, metallurgy, chemical industry, etc. The classification of deviation switches includes ordinary type, wiring chamber type, and address coding type. The ordinary type refers to the two-stage deviation switch mentioned above; The wiring chamber type deviation switch is equipped with a waterproof wiring chamber on the basis of the ordinary type deviation switch. The on-site control cable can be directly connected to the wiring chamber to prevent faults caused by moisture and virtual connection of cable joints. The address encoding type deviation switch integrates XLline fieldbus technology on the basis of ordinary deviation switches, achieving address encoding function. Suitable for remote monitoring of the operation of long belt conveyors as on-site equipment, it solves the inconvenience caused by workers searching for fault points. The address encoded two-level deviation switch is connected to the comprehensive protection device (gateway) through XLline fieldbus, supporting up to 128 addresses, and multiple switches can be used simultaneously at the same address. Its main feature is that it only requires a two core cable to complete data transmission simultaneously without the need for power supply. XLline fieldbus can finally achieve flexible connection with major manufacturers' PLCs and computer interfaces. Technical indicators 1. Rated voltage: AC380V2.
