Electromechanical relay module HR5S series

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&rsquo 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. Key Features: • The first category 2safety relay module in the industry • Ideal for low-risk machines • Safety with non-redundant safety circuit. • Push-in terminals save installation labor and prevent loosening of wires • Slim body save control panel space
