General Information

• Brand: Emerson
• Model: SE3007
• Product Type: Safety Relay Module (for industrial safety circuits)
• Safety Integrity Level (SIL): Compliant with SIL 3 (per IEC 61508) and Performance Level e (PL e) (per EN ISO 13849-1) – suitable for high-risk applications requiring maximum safety redundancy.
• Core Function: Monitors safety inputs (e.g., emergency stop buttons, light curtains, safety gates) and triggers safety outputs (e.g., machine shutdown, valve closure) when unsafe conditions are detected. Ensures failsafe operation with built-in redundancy and self-diagnostic features.

Technical Specifications

1. Input/Output Configuration

• Safety Inputs:
  • 4 normally closed (NC) safety inputs (compatible with emergency stop buttons, safety door switches, light curtains).
  • Input voltage: 24 V DC ±15% (industrial standard).
  • Input current: ≤5 mA per channel.
  • Monitoring: Cross-circuit and short-circuit detection between inputs to prevent false signals.
• Safety Outputs:
  • 3 normally open (NO) safety relay outputs (for controlling contactors, valves, or emergency stops).
  • Output rating: 250 V AC / 3 A (resistive load); 24 V DC / 3 A (resistive load).
  • Relay type: Force-guided (positive-guided) relays – ensures outputs cannot remain in a dangerous state during internal faults (per EN 50205).
• Auxiliary Outputs:
  • 1 auxiliary relay output (for status indication or non-safety alarms).
  • Rating: 250 V AC / 1 A; 24 V DC / 1 A.

2. Electrical Performance

• Power Supply: 24 V DC ±15% (1.2 W typical power consumption).
• Response Time: ≤15 ms (from input signal loss to output deactivation) – critical for stopping machinery quickly.
• Isolation: 2.5 kVrms between inputs, outputs, and power supply (per IEC 61131-2) – prevents electrical interference from affecting safety logic.

3. Physical & Environmental Specifications

• Dimensions: 22.5 mm (W) × 105 mm (H) × 75 mm (D) [0.89” × 4.13” × 2.95”] – compact DIN rail-mounted design, saving cabinet space.
• Mounting: DIN rail (35 mm standard) – easy installation in control panels.
• Operating Temperature: -25°C to +70°C (-13°F to 158°F) – suitable for harsh industrial environments.
• Storage Temperature: -40°C to +85°C (-40°F to 185°F).
• Humidity: 5%–95% RH (non-condensing) – resistant to moisture in washdown or humid areas.
• Vibration Resistance: 10 g (10–500 Hz) per IEC 60068-2-6 – withstands machinery vibration.
• Protection Class: IP20 (front panel) – designed for enclosed control cabinets.

4. Safety & Compliance

• Certifications:
  • CE (EN ISO 13849-1, EN 61508, EN 50205) – meets European safety standards for machinery and process safety.
  • UL 508S (industrial safety equipment) – compliant for North American markets.
  • cULus (Canadian and U.S. safety certification).
  • TÜV SÜD approval – verified compliance with global safety standards.

Key Features

1. High Safety Integrity: SIL 3 and PL e ratings ensure reliable operation in high-risk applications (e.g., robotic workcells, press machines, conveyor systems).
2. Failsafe Design: Force-guided relays guarantee that outputs switch to a safe state (e.g., de-energized) if internal faults occur (e.g., coil failure), preventing hazardous machine operation.
3. Comprehensive Diagnostics:
   • Built-in self-test (BIST) function continuously monitors relay contacts, input circuits, and power supply – detects faults and triggers auxiliary output alarms.
   • LED indicators: Power (green), safety circuit status (green), fault (red) – provide visual status for quick troubleshooting.
4. Flexible Wiring: Accepts parallel connection of multiple safety devices (e.g., emergency stops, safety gates) on a single input channel, simplifying system design.
5. Redundancy Support: Can be configured in redundant pairs (two SE3007 modules) for mission-critical systems – ensures safety function remains active if one module fails.
6. Easy Integration: Compatible with standard industrial safety devices (no special wiring required) and integrates with PLCs/DCS via auxiliary outputs for status monitoring.

Applications

• Machine Safety: Monitors emergency stop buttons, safety light curtains, and interlock switches on robotic arms, packaging machines, and CNC equipment – triggers immediate shutdowns when hazards are detected.
• Process Safety: Controls emergency shutdown (ESD) valves in chemical plants or refineries – isolates hazardous materials if pressure/temperature limits are exceeded.
• Material Handling: Ensures conveyor systems or lift platforms stop when safety gates are opened or overloads are detected.
• Automotive Manufacturing: Protects workers near assembly line robots by monitoring perimeter safety barriers and emergency stops.

Documentation & Support

• Technical Manual: Emerson SE3007 Safety Relay Module Installation & Safety Manual (Document No. SE3007-UM-001) – available via Emerson’s official support portal, including wiring diagrams, safety circuit design guidelines, and fault troubleshooting.
• Safety Certification Data: Detailed compliance reports for EN ISO 13849-1 and IEC 61508 are provided with the module.
• Spare Parts: Replacement relays and terminal blocks are available via Emerson’s authorized distributors.
