Wieland 24V ac/dc Safety Relay with 3 Safety Contacts, 1 Auxiliary Contact, Manual Reset, DIN Rail Mount R1.188.1810.0

Wieland R1.188.1810.0 Safety Relay is an advanced safety control device operating at 24V ac/dc voltage, designed for critical industrial safety applications including elevators, heaters, and machinery requiring emergency stops or safety gate monitoring. It incorporates three normally open safety contacts and one auxiliary contact, mounted conveniently on DIN rails for streamlined installation in industrial control panels.

This safety relay features a manual reset function, providing controlled operation after safety events, and a time delay of 350 milliseconds to ensure precise contact timing during switching operations. With a compact form factor measuring 96.5mm in height, 22.5mm in length, and 114mm in width, it is suitable for space-constrained installations while maintaining robustness.

The device supports operation across a temperature range from -25°C up to 65°C, and power consumption is efficient at only 1.6 watts. It is built to withstand industrial environments with an IP40 rating, though it is not certified for hazardous areas. LED indication provides straightforward status verification to operators.

Designed according to stringent standards such as EN 62061, EN ISO 13849-1, EN 81-1, and EN 50156-1, and approved by leading certification bodies including TÜV and cULus, this safety relay meets high safety category 4 requirements. It is compliant with Stop-Category 0 acc. EN 60204-1 and can be applied for SIL 3 safety integrity level applications per EN 62061 and PL e according to EN 13849-1.

Typical applications include use as an emergency stop device, safety gate monitor, and general safety relay functions in industrial automation systems, elevators, and heating control circuits. The device supports one or two-channel wiring and includes external device monitoring capability for enhanced safety oversight.

Mount type is DIN Rail with screw terminals allowing secure and flexible installation with an 8A contact current rating, switching DC voltage of 24V dc, and switching AC voltage of 230V ac. This product is manufactured in Germany, ensuring high-quality engineering and reliability.
