SICK 1099969, also known as RLY3-OSSD300 from the ReLy range, is a compact industrial safety relay designed for evaluating safety sensors with OSSD outputs. It operates from a 24 V DC PELV or SELV supply and provides two safety inputs, one reset or external device monitoring input, three positively guided normally open enabling current paths, two non-safe diagnostic outputs and one non-safe test pulse output. With SIL 3, PL e and Category 4 ratings, the RLY3-OSSD300 is suited to machinery control panels where dependable monitoring of protective devices is required. Its hard-wired configuration, front connector with spring terminals and narrow 18 mm housing make it practical for DIN rail installations with limited panel space. The unit features automatic and manual reset functions, restart interlock, sequence monitoring and EDM capability. Key electrical characteristics include a 12 ms response time, 10 V to 230 V AC/DC switching voltage range, switching current from 10 mA to 6 A and a total current rating of 12 A. The relay is built for industrial environments, with an IP20 enclosure rating, operating temperature range of -25 °C to +55 °C and mechanical life of up to 10 million switching cycles.
Typical applications
- Evaluation of OSSD signals from compatible protective sensors
- Integration of light curtains and light grids into machine control circuits
- Monitoring access points on automated machinery and production cells
- Enabling controlled stop functions for industrial equipment
- Restart interlock control after a protective device has been activated
- External device monitoring for contactors and downstream switching devices
- Use in control panels requiring compact DIN rail mounted relay modules
- Providing positively guided relay outputs for machine shutdown circuits
- Diagnostic signalling to PLCs or indicator systems via non-safe outputs
- Sequence monitoring in industrial automation applications
