Motion axes in event technology usually have to meet functional safety requirements. Different manufacturers of axles and controllers have different approaches. TR has been offering suitable multi-channel absolute encoders for a wide variety of structures for years. Certified components make acceptance of the entire system easier. The safe rotary encoders of the CD_582+FS family perfectly meet the requirements of the event industry: in the compact installation space of a standard 58 mm industrial encoder there is a truly absolute multiturn double encoder system with integrated safety evaluation, which directly outputs secured position data ("safe position" - SLP). Depending on the version of the rotary encoder for the highest safety level SIL3 or PLe or as a version adapted to the requirements for SIL2 / PLd applications. This ultra-compact SIL rotary encoder fits into a wide variety of mounting situations: With the solid shaft, a slot and a feather key ensure the necessary form fit between the application and the sensor, with blind hole shafts and through hollow shafts up to 15 mm, a slot in the hollow shaft.
Depending on the control environment, CD_582+FS supports different interfaces:
- PROFINET/PROFIsafe
- Ethernet/IP with CIPsafety
- Powerlink with OpenSAFETY
- CANopen safety according to CiA DS304

Wherever a standard 58 mm encoder is used, the CD_582+FS can be used to provide an axis, a system module or a machine with safety functions in accordance with the current basic and implementation standards. In principle, the CD_582+FS fits anywhere where the non-functionally safe CE_582 and CM_582 can also be installed. With CD_582+FS, the use of certified safe components is no longer a question of installation space.

Wire draw encoders by TR-Electronic are equipped with absolute or incremental rotary encoders and fit the specific encoder series perfectly. Three classes fulfill specific needs for different mechanical loads, duty cycle, lifetime, resolution resp. reproducibility. Typical application in stage technology is position detection of lifting platforms.

The SL 30 is designed for many years of use with a high activity rate. With a big number of options, the system can be adapted to many applications.

With notion.ABC from TRsystems, both machine modules and entire systems are suitable for Industry 4.0. Thanks to multi-touch, innovative operating panel technology is combined with TRsystems' many years of experience in creating robust control systems for particularly demanding environments.

The notion.A device design was conceived for the operation of systems where the
machine operator or plant operator requires a direct view of the work area.
Thanks to the close proximity, they can monitor processes via the user interface of the application software and intervene directly in the process.
The device is typically attached to a support arm with a VESA 75/100 mount. The electrical connection technology varies from conventional plugs to robust M12 connectors. Precautions have been taken to ensure that notion.A can withstand exceptional mechanical stresses such as vibration and shock. The fanless and easy-to-clean notion.A has display diagonals from 256.5 mm (10.1") to 546.1 mm (21.5") with a multi-finger touch system. The housing can be equipped with 22.5 mm operating elements such as emergency stop buttons and signal and indicator lights.

CR_582 - housing 58 mm
One housing, two independent rotary encoders, many flexible safety concepts!

The requirements for reliability, availability and safety of machines and systems are increasing. Users meet the requirements with strategies for the design of the machine, system and control technology that are adapted to the application. TR-Electronic has set itself the goal of supporting a wide variety of structures and strategies with high-quality technical solutions. In addition to the SIL/PL-certified sensor solutions, there are also redundant versions that also enable other safety and high-availability concepts in the design.
The CR_582 family integrates two rotary encoders in the space of a standard industrial encoder with a size of 58 mm. The position values are determined by two independent sensors and processed separately. Both sensors can also be parameterized differently from each other. The encoder transmits the values either via SSI, incremental or CANopen interface.
The two channels of In SSI/SSI and SSI/incremental variants are completely independent of each other and are even galvanically isolated. With CANopen there are two participants in the bus. The CAN signals are galvanically isolated from the supply.
The scanning technology used offers high reliability: the characteristic value determined during the analysis exceeds the requirements for avoiding common cause failures. The user relies on the characteristic value for the design of safety functions. He now has all the freedom to evaluate the two independently determined and transmitted measured values ??in terms of availability, safety and diagnostic coverage in his control. Mechanically, the CR_582 is available as a solid shaft device, with a blind shaft and with a directly attached cable pull for measuring lengths of up to 40 m. The connections are on the side of the device; Thanks to the plug design and coding, dangerous mix-ups when connecting are ruled out, even if access is difficult.
Users of TR encoders from the CR_58 family benefit from the wide range of services from many years of consistent customer orientation:
Matching outboard bearings allow use with higher shaft loads. The measured values can be scaled with numerator/denominator; this means that there are no rounding errors even with rotating, repeating axes. If the rotary encoder is sold with a cable attached, the zero point of the output is adjusted to the zero point of the range of motion of the cable mechanism.
These and many other features from the standard portfolio of TR-Electronic turn a standard rotary encoder into the perfect sensor for a specific application.
