The motrona SRC30/EL is a compact, high-performance safety relay designed for emergency stop and safety gate monitoring in demanding industrial and elevator applications. Certified to the highest safety standards, including SIL3 (IEC 61508), PLe / Category 4 (EN ISO 13849-1), and EN 81-20/50 for elevators, the SRC30/EL ensures reliable protection for personnel and machinery.

Flexible Configuration for Diverse Applications

The SRC30/EL supports both single-channel and dual-channel operation, adapting to various safety circuit requirements. It features three instantaneous safety contacts (NO) and one instantaneous signaling contact (NC), providing comprehensive switching capabilities. The device is compatible with a wide range of safety input devices, including emergency stop buttons, mechanical safety switches, non-contact safety switches, and safety components with OSSD outputs.

Comprehensive Monitoring and Diagnostic Functions

The safety relay includes a feedback loop for monitoring downstream contactors or expansion modules, ensuring the integrity of the entire safety chain. Cyclical monitoring of the output contacts detects potential faults before they compromise safety. Cross-circuit and earth fault monitoring further enhance system reliability. Status and power indicators via LEDs enable quick diagnostics without computer support.

Easy Integration and Operation

The SRC30/EL offers selectable automatic or manual start, providing flexibility to respond to different safety requirements. Its compact housing is designed for mounting on a 35 mm top-hat rail (EN 60715), with a low height that facilitates installation in space-constrained control cabinets. The simple handling and fast response time enable quick integration into existing systems.

Ideal for Elevator and Safety Gate Monitoring

With its EN 81-20 and EN 81-50 certifications, the SRC30/EL is perfectly suited for elevator monitoring applications, including safe light grid monitoring and automatic goods elevator safety. At the same time, it offers an excellent solution for safety gate monitoring of machines and systems, as well as a wide range of industrial automation applications such as conveyors, robotics, and mechanical engineering.
