Safetec BG02.510 – Compact Safety Relay for E‑Stops and Guard Monitoring

The Safetec BG02.510 is a compact, DIN‑rail safety relay designed to supervise emergency stop buttons, gate interlocks, and other dual‑channel safety devices. From my experience, modules in this format are typically used when you want SIL/PL‑rated protection without the complexity of a safety PLC—just reliable, force‑guided contacts that stop the machine when they should. You might notice that it fits neatly into tight panels and doesn’t ask for any programming, which keeps commissioning quick and predictable.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: 1 week for in‑stock; no more than one month at the latest
• Payment terms: 50% advance payment, full payment before delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• Dual‑channel safety input – Monitors E‑Stop or guard switch channels with cross‑fault detection for higher integrity.
• Force‑guided safety outputs – Redundant NO safety contacts for direct control of contactors or STO inputs.
• Manual or automatic reset – Selectable reset mode to match your risk assessment and local practices.
• Compact 22.5 mm housing – Saves panel width; typically fits standard control cabinets without rework.
• DIN‑rail mounting – Quick installation on EN 60715 rails; screw terminals simplify wiring.
• Status indication – Front LEDs make troubleshooting fast during commissioning and audits.
• Broad device compatibility – Works with common E‑Stops, keyed interlocks, and safety switches used across packaging and metalworking lines.

Technical Specifications

Application Fields

This model fits well in packaging machines, metalworking cells, assembly stations, intralogistics conveyors, and small process skids. In many cases, integrators pair it with standard E‑Stops and tongue interlocks on access doors, using the relay to drop out motor contactors or trigger STO on drives. One thing I appreciate is how it simplifies retrofits; you can add a guard switch to an existing line and tie it into the BG02.510 without reprogramming the PLC.

Advantages & Value

• Reliability first – Force‑guided contacts and dual‑channel logic reduce single‑fault risks during emergency stops.
• Straightforward integration – No software; wiring diagrams are clear and commissioning is usually under an hour.
• Panel space savings – 22.5 mm width keeps enclosures smaller, which can cut cabinet and cooling costs.
• Compatibility – Works with mainstream E‑Stop buttons, keyed/tongue interlocks, and safety contactors used by most OEMs.
• Lifecycle cost – Minimal maintenance, easy spares stocking, and fast swap‑outs reduce downtime penalties.

Installation & Maintenance

• Cabinet & environment – Mount on a grounded DIN rail in a ventilated cabinet; keep ambient within the specified temperature range and away from vibration where possible.
• Wiring – Use dual‑channel wiring for safety devices; separate safety and power wiring; follow the recommended conductor sizes and torque values.
• Reset & EDM – Configure manual reset for guard doors; wire External Device Monitoring (feedback loop) to verify contactor drop‑out.
• Safety checks – Perform regular functional tests (E‑Stop and gate open tests) and log results; visually inspect terminals and relays for wear.
• Maintenance – Dust the module periodically; check for heat discoloration on contacts; replace contactors at end‑of‑life to protect relay outputs.

Quality & Certifications

The BG02.510 follows the typical safety‑relay design practices for CE application and is usually paired with cULus‑recognized components in North America. RoHS alignment is expected for modern control gear. Safety performance for systems using this relay commonly targets ISO 13849‑1 (up to PL d/e depending on the architecture) and IEC 61508/62061 categories when wired correctly. Warranty coverage is 365 days from shipment.

Supporting Components (often paired)

• Emergency stop buttons – 40/60 mm mushroom E‑Stops with positive‑opening NC contacts.
• Guard interlock switches – Tongue/keyed switches or solenoid‑locking types for access doors.
• Safety contactors – Contactors with mirror contacts for EDM feedback to the BG02.510.
• DIN rail accessories – End stops, terminal markers, and ferrules for neat, reliable wiring.
