Successful Safety Certification of TTControl’s Safety I/O Modules

TTControl has completed the safety certification of its newly launched CANopen Safety I/O modules. Two variants of the HY-TTC 30X family – HY-TTC 30XSH and HY-TTC 30XSI – have been assessed and certified in accordance to EN ISO 13849-1:2008 (Performance Level c) by TÜV NORD. At the same time the EC-type examination has been completed and approved and the EC declaration of conformity has been issued.

The modules can be used as I/O extensions for safety-relevant functions of control systems for mobile machinery. The standardized CANopen Safety protocol is used for communication with the master controller. TTControl’s customers benefit from the TÜV certification: As an off-the-shelf module delivered with a ready-to-run software it can easily be integrated into a safety-relevant system. The relevant hardware metrics (MTTFd and DC values) of the module are available on an I/O level, therefore the performance level for the whole system can be easily determined as well.

All modules of the HY-TTC 30X product family are protected by a compact aluminum die-cast housing which is highly suited for rough operating conditions. They also provide a wide range of configurable I/Os and allow local current control for its PWM outputs. All I/O slave modules are delivered with a ready-to-run software and an electronic datasheet (EDS-File). When the master is programmed in CODESYS® the EDS-File can be easily imported into the CODESYS development environment. This makes the setup user-friendly and saves development time. For safety requirements beyond PL c TTControl also offers an I/O module solution for up to PL d with the HY-TTC 48XS module.
