The RLY3-0SSD200, RLY3-OSSD200, 1085344, and RLY3OSSD200 are interchangeable names for a safety relay model produced by Omron Automation and Safety. This relay is designed to meet the stringent safety requirements of industrial automation applications.
This safety relay is a type 2 (normally open) two-contact, 2-form C, SIL3 rated device, which signifies it can be used in applications demanding the highest level of safety integrity. It is engineered to provide reliable and secure operation in the event of a fault or failure, ensuring operator and equipment safety.
The RLY3-0SSD200 features an SOS (Safety Output Supervision) function, which monitors the safety output status continuously and sends an alarm if any abnormal behavior is detected. This function helps prevent potential hazards and ensures the safety system remains functional.
The relay comes with a built-in diagnostic function, which enables easy fault detection and troubleshooting. This function illuminates an LED indicator, showing the status of the safety output and the relay's internal diagnostics.
The RLY3-0SSD200 is designed for easy integration into various safety applications, thanks to its compact size and versatile mounting options. It can be mounted on a DIN rail, on a panel, or on the sidewall. It also features a screwless terminal block, which simplifies wiring and reduces installation time.
This safety relay offers a high operating speed of 0.1ms, ensuring quick response times and effective control of safety functions. It can handle a maximum current of 20A and a maximum voltage of 24V DC. Additionally, it is designed to operate in a temperature range of -25 C to 70 C, providing reliable performance under various environmental conditions.
In summary, the RLY3-0SSD200, RLY3-OSSD200, 1085344, and RLY3OSSD200 are interchangeable safety relays from Omron Automation and Safety. They are SIL3 rated, feature SOS and diagnostic functions, and offer fast response times and easy installation.
