LS SR Safety Relay
The LS SR Safety Relay is a DIN-rail-mounted functional safety device designed to monitor emergency stop pushbuttons, safety gate switches, light curtains, and two-hand control devices in machinery safety circuits in accordance with EN ISO 13849-1 and IEC 62061 standards. The SR103MPI achieves Safety Integrity Level 2 (SIL 2) and Category 4 / Performance Level e (PLe) — the highest machine safety category — making it suitable for guarding the most hazardous machine operations including press tools, robotic cells, and high-force clamping machinery. The relay features dual-channel safety input monitoring, cross-fault detection, and a manual or automatic reset function with selectable start mode, allowing it to be configured for the specific risk assessment requirements of each machine without additional external components.
The SR103MPI provides three safety output contacts (2NO + 1NC) rated at 6 A / 250 V AC, capable of switching motor contactors, brake solenoids, and pneumatic valve coils directly in most applications. Response time from safety input de-energisation to output contact opening is under 10 ms, meeting the response time requirements of guard monitoring and emergency stop circuits across the full range of industrial machine speeds. The relay is powered from 24 V DC and features LED status indicators for input, output, and fault states on the front face, enabling rapid fault diagnosis without measurement equipment. IEC 61000-4 series EMC immunity ensures reliable operation in electrically noisy panel environments containing variable speed drives and motor starters.
Saudi Arabia's National Labour Law and SASO machinery safety standards increasingly align with European CE Machinery Directive requirements, particularly for machinery imported under Vision 2030 manufacturing investment programmes. Safety relay usage is mandated in robot integration projects, press shops, and automated assembly lines at automotive component manufacturers and electronics assembly facilities in industrial cities across the Kingdom. ARAMCO's facilities engineering standards also require SIL-rated safety functions for rotating equipment isolation and emergency shutdown sequences at upstream and downstream processing facilities. The SR103MPI's IEC-compliant certification package simplifies the CE/SASO approval documentation process for Saudi-based machine builders and importers.
Razz Middle East maintains stock of SR103MPI safety relays for fast delivery to safety system integrators and machine builders throughout Saudi Arabia. Our engineers provide safety circuit design review and risk assessment consultation services, helping customers achieve the correct PLe/SIL rating for their machine guarding applications. SAR pricing is available with volume discounts for safety system panel builders. All units carry the LS Electric two-year manufacturer warranty and arrive with full IEC compliance documentation.

Key Features & Benefits
- SIL 2 / Category 4 / PLe certified per EN ISO 13849-1 and IEC 62061, covering the full range of machine guarding applications from light fencing to the most hazardous press and robot installations.
- Dual-channel safety input monitoring with cross-fault detection identifies wiring faults and short-circuits between channels before they can compromise the safety function.
- Under 10 ms response time from input de-energisation to output contact opening meets guard monitoring requirements for high-speed machinery without additional timing relays.
- Selectable manual or automatic reset modes with monitored start capability prevent automatic machine restart after a guard is opened — a common ARAMCO and SEC facility safety requirement.
- Three output contacts (2NO + 1NC) rated at 6 A / 250 V AC switch motor contactors, brake solenoids, and valve coils directly, eliminating the need for auxiliary relay amplifiers in most circuits.
- LED indicators for input, output, and fault states on the front face enable rapid fault diagnosis and maintenance without test equipment, reducing machine downtime after a safety event.
Industrial Applications in Saudi Arabia
- Emergency stop monitoring circuits on CNC machine tools, machining centres, and automated assembly lines in MODON industrial city manufacturing facilities throughout Saudi Arabia.
- Safety gate and interlocked guard monitoring on robotic welding and assembly cells at automotive component and electronics manufacturing plants under Vision 2030 investment programmes.
- Light curtain and two-hand control monitoring on hydraulic and mechanical press tools in metal fabrication workshops across Saudi Arabia's industrial sector.
- Rotating equipment isolation safety circuits at ARAMCO and SABIC process plants where SIL-rated emergency shutdown functions are required by facilities engineering standards.
- Conveyor system emergency stop networks in food, beverage, and logistics facilities where EN ISO 13849-1 PLe compliance is required for CE machinery marking.
