Intrinsically Safe (I.S.) Radio Remote Controls

For wireless control in the most volatile environments, FJS Consulting manufactures and supplies MASC-certified Intrinsically Safe Transmitters. These units are specifically engineered for use in Group I (Mining) and Group II (Surface) hazardous locations where explosive gases or dust are present.

Protection Type: Certified as Intrinsically Safe [Ex ia], ensuring that any electrical or thermal energy is limited to levels that cannot ignite an explosive atmosphere.
Ruggedized for Industry: Built to withstand the harsh conditions of South African coal mines and petrochemical plants.
Ergonomic Design: Available in various configurations to suit machine-specific controls while maintaining operator safety and comfort.
Standards: Fully compliant with SANS 60079-0 (General Requirements) and SANS 60079-11 (Intrinsic Safety).
Local Implementation: Meets the regulatory requirements of the Mine Health and Safety Act and the Occupational Health and Safety Act.

Intrinsically Safe Sensors

Our MASC-certified intrinsically safe barriers provide critical protection for power and data lines entering hazardous locations. Designed and manufactured in-house by FJS Consulting, these units ensure that electrical energy is limited to prevent the ignition of explosive atmospheres.

Power & Communication Barrier: A dual-purpose barrier housed in a non-metallic enclosure. It provides essential protection for both power lines and RS485 communication lines.
RF Barrier: Specialized protection for high-frequency output lines. Housed in a metallic enclosure and fully encapsulated, it is specifically designed to safely power antennas in volatile environments.
Ex Marking: $[Ex\ ia]\ I$ (Intrinsically Safe for Mining).
Certification Standard: Fully compliant with SANS 60079-11: 2024 for intrinsic safety.
Installation: Designed to be installed within a flameproof enclosure for maximum secondary protection.

Flameproof Enclosures & Control Panels

We design, assembly, and supply of Flameproof Enclosures engineered to contain any internal explosion and prevent the ignition of the surrounding atmosphere. Our panels are the preferred choice for housing PLCs, motor starters, and radio receiver interfaces in coal mines and petrochemical plants.

Protection Classes: Ex d (Flameproof), Ex e (Increased Safety), and Ex t (Dust Ignition Protection).
Material Options:
- Copper-Free Aluminium: Lightweight and corrosion-resistant for general underground use.
- 316 Stainless Steel: Essential for the corrosive coastal environments of the Western Cape.
Entries: Customized drilling and tapping for Ex-rated cable glands (NPT or Metric).

Ex-Rated Solenoid Coils

We provide high-durability, explosion-proof solenoid coils designed for hazardous gas and dust environments. These coils are the heart of reliable hydraulic and pneumatic valve control in volatile areas

Certifications: ATEX, IECEx, and SANS/MASC approved for Zone 1 and Zone 2.
Protection Types: Available in Flameproof (Ex d), Encapsulated (Ex m), and Intrinsically Safe (Ex i) configurations.
Voltages: Standard ranges include 12V DC, 24V DC, 110V AC, and 230V AC.
Duty Cycle: 100% continuous duty rating to ensure zero downtime in critical operations.
Ingress Protection: IP66/67 rated for harsh, wet, or dusty underground conditions.
