TR Electronic’s CDx Series Absolute Encoders deliver high system performance with a low probability of failure and features a Safety Integrity Level of 3 (SIL3). The CDx Series is also suitable for applications that need redundancy with diverse combinations of interface options available.
On top of that, the CDx Series features options for a solid shaft (CDV 75mm) and hollow through shaft (CDH 75mm). Both options have two channels and come with either Fieldbus or SSI interfaces.
The CDx Series with SSI have two redundant SSI interfaces, namely a safety system and a master system. The safety system features an overall resolution of 25 bit, 8,192 steps per revolution across 4,096 revolutions. Safety is assured in connection with controls certified as SIL3 compliant and monitoring conditions defined by TR.
On the other hand, the master system features an overall resolution of 25 bit, 8,192 steps per revolution across 4,096 revolutions. It also utilizes incremental signals or SIN/COS signals for position feedback.
Meanwhile, the CDx Series with PROFIsafe protocol utilizes either a PROFIBUS-DP or PROFINET-IO interface with two redundant scanning principles. It comprises dual channel magnetic and optical scanning systems. Velocity values and safety position are only transmitted when an internal cross comparison is completed.
In addition, this system has an overall resolution of 28 bit, 8,192 steps per revolution across 32,768 revolutions and utilizes SIN/COS signals or incremental signals for position feedback.
Furthermore, all CDx options have a Protection Class rating of IP 54. They can work in temperatures ranging from 0° to +60° Celsius; while some variants can work between 20° and +70° Celsius, but with restricted functionality.
