Large machines are generally long-term investment items and can oftenbe used mechanically long beyond the service life of individual controlsystem components. However, in order to also be able to continue usingthese, adaptations to new bus systems and current standards usuallyneed to be made.
System integrators that have to unite machines of all kinds to form a functioning production line also face similar problems. With the GND reading digital input modules of the Helmholz TB20 I/O system it is possible to update many existing machines to the latest standard at an optimized price and prepare them for international use. Labor-intensive rewiring is dispensed with in the process.
Three-component module design
TB20 I/O modules have three components: a separate front connector, an electronic module, and a base module. A locking mechanism ensures that all modules can be quickly mounted and securely attached on DIN rails while guaranteeing a reliable electrical connection. Likewise, all modules can be easily and quickly removed for maintenance and/or system expansions. Modules are delivered as complete assembled units (i.e., as a single assembly) and can be installed immediately. This makes keeping expensive special parts in stock obsolete.
Hot-plug capability Individual modules can be replaced quickly and easily while the rest of the system keeps running. The hot plug-compatible electronic module helps keep downtimes to a minimum.
The integrated rotary coding system prevents users from plugging in this slot incorrect modules, ensuring that modules can be replaced in a fool proof manner. This not only helps prevent damage to the system, but also system malfunctions.
