SM-Safety - .PDF file.

Control Techniques has developed SM-Safety, a programmable plug-in option for the company’s drives that offers high levels of machine safety.

Keeping up to date with the new standards for safety-related control systems such as EN 61800-5-2 with functions such as Safely Limited Position (SLP) can be complex and time-consuming.

In a single plug-in option module, SM-Safety is said to provide a complete range of functions that are ideally suited to being implemented within a drive, increasing functionality, speed of reaction, and reducing the overall cost.

SM-Safety is a programmable option module that, when plugged into a Control Techniques Unidrive SP AC drive or the Digitax ST servo drive, frees engineers’ time to do more.

Using the free Control Techniques’ software, CTsafelite – or for more advanced applications, CTsafepro – designers or users can build a comprehensive bespoke safety protection zone to meet the safety needs of the machinery.

SM-Safety meets international safety standards EN 61508, EN 62061, EN ISO 13849-1 and, most important with respect to drives, EN 61800-5-2 adjustable speed electrical power systems – Part 5-2: Safety requirements – functional.

SM-Safety has a total of 18 I/O ports comprising four dual redundant digital inputs, one single digital input, three safe digital outputs, two additional digital outputs, two inputs dedicated to incremental or absolute position sensors (encoders) and pulse outputs.
