Product Overview

Mine Safety Coupler is a dedicated safety signal processor for mine communication, commonly referred to as a safety barrier.Safety device for converting non-intrinsically safe signals into intrinsically safe signals。The KTA758 safety coupler utilizes modern electronic technology and is a high-performance, high-reliability mine safety isolation circuit developed with full integration circuits. The KTA758 safety coupler is used in conjunction with intrinsic safety push-to-talk phones to form a production dispatching and command telephone system for explosion-proof areas. Each box contains 32 safety circuit users, a 2U chassis, with simple installation and minimal space usage. Signal input/output interfaces use DB37 connectors, with male and female heads offset for easy maintenance; simply connecting the input/output DB37 connectors can confirm if the coupler is functioning normally. Output of the KTA758 safety couplerBoxKTJ102 General MiningSupplementary equipment for explosion-proof type digital programmable dispatching machines (mandatory for users in explosion-proof zones).

Product Features

Convert the bell stream signals, urgent call signals, hang-up prompts, etc., transmitted by the dispatch communication system into inherently safe signals that the intrinsic safety telephone function can accept.

2、TranslateEssential safety telephones convert off-hook signals, dial pulse signals, dual-tone multi-frequency signals, and emergency call signals into formats acceptable by dispatch exchange systems.

3、Schedule Communication SystemThe non-safe supply voltage is converted to a supply voltage acceptable by the inherently safe telephone function.

4. Transmitting two-way voice signals.

5. Achieve bidirectional conversion of various detection signals between the scheduling communication system and intrinsic safety telephones.
