Safety Relay Module
Safeguarding people and equipment with a properly designed system that monitors all of your safety devices is a top priority. IDEC offers straightforward, easy to use and highly efficient safety control relay modules in a variety of styles to help meet this need. HR1S safety relays are compact units that monitor safety input devices, allowing machine operation only when all safety controls are working correctly and no hazardous conditions are detected. Supported devices include E-stops, interlock switches, and noncontact safety switches, with light curtains covered on certain models. The HR2S series safety relays provide users with increased functionality and flexibility when designing systems to meet safety requirements.
The first category 2 safety relay module in the industry
Machine safety design is a detailed topic addressed by many regulations and standards, and it is also supported by numerous specialty products and practices.
However, this doesn’t ensure appropriate machine safety measures are always applied. There is a strong tendency among many designers to presume that machinery must come to a full stop when errors are detected. This belief, along with overly conservative interpretations of ISO standards, has led many designers to handle most situations as category 3 or 4, requiring full redundancy. In 2015, ISO 13849 was revised and the requirements for category 2 were updated becoming easier for users incorporate into their machine safety systems.
Instead of mandating full redundancy as with categories 3 or 4, when category 2 is acceptable, only single input connections, less expensive controllers, and single outputs can be used. Design effort is reduced, the safety controllers relay modules are more economical, fewer and less-specialized non-redundant devices can be used, control panel space is saved, and field installation labor is reduced.
CATALOGHR1S safety control relays are compact units designed to monitor safety input devices, which allow machine operation only when all safety controls are functioning properly and hazardous conditions are not detected. Supported safety devices include E-Stops, interlock switches and non-contact safety switches. These relays have either instantaneous (STOP 0) or time delayed (STOP 1) relay safety outputs, as well as solid-state outputs for use with diagnostics, troubleshooting and correct system operation. In addition, front panel LEDs can be used for monitoring the current status and most models are available in a variety of monitoring configurations, including removable terminals, monitored start, and single- or dual-channel operation.
The HR1S series of safety control relays provide increased functionality when designing equipment to meet global safety requirements in the U.S. and Europe, while adhering to EN ISO 13849-1 PLe, Safety Cat 4 and EN 62061 SIL 3.
The HR2S series safety relays provide users increased functionality and flexibility when designing system to meet safety requirements. HR2S safety relays are compact modules designed to allow machine operation only when all safety controls such as Interlock Switches, E-stop switches, Light Curtains, etc. are functioning properly and aren’t reporting hazardous conditions. The HR2S feature removable terminals for easy wiring and installation, and time delay circuit.
