Product Overview
The Intrinsically Safe Mining Pneumatic Turnout Controller is designed for turnout control in underground mines, intended for automatic or manual turnout operation. Powered by 12 VDC with working current strictly limited to ≤305 mA, it controls power consumption and helps maintain intrinsic safety, supporting dual control-input methods.
Product Description
Track turnouts in underground mines switch locomotives and material cars between roadways, and controlling them reliably — from a safe distance and in a hazardous atmosphere — is essential for efficient and safe haulage. The Intrinsically Safe Mining Pneumatic Turnout Controller is an intrinsically safe device designed for this purpose, intended for automatic or manual turnout operation.
The controller is powered by 12 VDC, providing the basic rated voltage required for stable operation. Its working current is strictly limited to ≤305 mA, which controls power consumption and, critically, helps maintain intrinsic safety by keeping the electrical energy available at the device within safe limits. This disciplined energy design allows the controller to operate in gas-risk underground environments.
The controller supports dual control-input methods for flexible field application: it can be triggered automatically by the mine control system as part of the signaling scheme, or operated manually by personnel when required. This flexibility means the same controller adapts to fully automatic haulage systems and to simpler manual layouts, giving mines a single hardware platform for turnout actuation.
