Product Description
MTL7788 Intrinsically Safe Zener Safety Barrier Encoder DIN Rail Mounting
MTL7788+ | Instruments | Proximity Detector Interface
The MTL7788+ is a DIN rail mounting isolation barrier from the MTL7700 series of safety barriers. This professional-grade component offers reliable protection for industrial applications in hazardous areas.
Key Features:
- Removable terminals for easy installation and maintenance
- Bus power supply capability for other modules
- Supports relay and solid-state switching modules
- Dual channel variants with 6.3 mm per channel spacing
- Proximity detector inputs for enhanced functionality
- Electronically fused for added protection
- Direct replacement for MTL700 range barriers
- Compatible with terminal numbers and safety instructions
Safety Design Principles:
All MTL7700 series Zener barriers follow the same robust design principles. Each channel includes:
- Secondary pulse detecting Zener or forward connecting diode
- Reliable terminating resistor for current limitation
- Two-stage voltage limiting function for continuous protection
- Fuse protection for the diode
In the event of an electrical fault in the safety zone, the diode limits hazardous area voltage while the resistor limits current. No active output current limiting circuitry is used.
Certifications:
Certified "ia" for all zones and "IIC" for all explosive atmospheres (except MTL7707P+ and MTL7729P+, which are "ia" "IIB").
