# First CIP Safety over EtherNet/IPTM Encoder that is capable of up to SIL 3/PL e

843ES CIP Safety over EtherNet/IP™ Encoders are designed for safety applications that require speed, direction, or position monitoring safety functions.

These encoders support the GuardLogix® controller-based safety functions, according to IEC 61800-5-2, in the Studio 5000 Logix Designer® application. The 843ES CIP Safety Encoder can support advanced safety solutions using STO-supported drives or servos, safety controllers, and already available drive safety instructions.
