Relay 4 SIL2 – Safety Digital Output Module
Relay 4 SIL2 is a compact safety-capable digital output module designed for reliable switching and control of external devices in industrial automation and functional safety applications. The module provides four independent relay outputs, enabling controlled actuation of alarms, beacons, sounders, indicators, interposing relays, and other field equipment where dependable output control is required. Relay 4 SIL2 connects directly to the system backbone and is optimized for use with MicroHub and NanoHub-based architectures. The module supports distributed control and scalable I/O expansion, making it suitable for modular safety, Fire & Gas, monitoring, and automation systems where reliable and traceable output actuation is an important part of the system design. With redundant power and communication available via the backbone, Relay 4 SIL2 supports improved system availability and robust operation in demanding environments. The module is designed to form part of SIL2-capable Mimes system architectures, supporting safety-related output functions when implemented, validated, and maintained according to the applicable functional safety lifecycle requirements. The compact DIN rail format makes Relay 4 SIL2 easy to integrate into control cabinets, junction boxes, and distributed field panels. It is designed for industrial, marine, energy, infrastructure, and safety-related installations where flexible digital output control, diagnostics, and scalable system expansion are required.
