Renishaw, the global engineering technologies company, builds on its existing functionally safe (FS) portfolio by introducing two new encoders for both linear and rotary applications.
RESOLUTE™ FS with BiSS® Safety absolute open optical encoder system, and TONiC™ FS incremental open optical encoder system.
The RESOLUTE Functional Safety (RESOLUTE FS) optical absolute encoder is based on the design of the award winning RESOLUTE series with elements redesigned to meet FS safety standards.
The TONiC Functional Safety (TONiC FS) optical encoder combines full FS compliance with the exceptional metrology performance, ultimate reliability and other benefits of the established TONiC encoder range.
Both the RESOLUTE FS BiSS Safety encoder and the TONiC FS encoder are certified to ISO 13849 Category 3 PLd, IEC 61508 SIL2 and IEC 61800-5-2 SIL2.
Full FS certification is required to guarantee the safe use of functions that include safe stops 1 and 2, safe operating stop (SOS) and safe limited speed (SLS) — all of which require functionally safe encoder feedback. RESOLUTE FS encoders are compatible with the open source BiSS Safety serial communications protocol and Siemens’ Drive-CLiQ protocol. TONiC FS encoders are available with the TONiC Ti-000 analogue interface and Dual Output (DOP) interface options.
