IO-Link converter for analog signals


IO-Link converter for analog signals

In most systems and machines, analog signals account for only a few percent of the available data volume. Their connection and integration, however, cause high costs. Not so with the new IO-Link converters for analog input and output signals. They open up a noticeable cost savings potential for systems with limited analog value volumes. Instead of expensive shielded cables, simple unshielded 3-wire standard cables can be used. Distribution boxes or expensive analog interfaces are no longer required, as are additional interface boxes. A further advantage is that the change from analogue to digital data transmission significantly increases process quality.

With the new IO-Link converters, different input, output, current and voltage signals can be used on one module with maximum signal variance. Depending on the version, the analog port can be configured for a voltage signal, a current signal, a Pt sensor or a thermocouple. Current/voltage interfaces are available in different versions: 0…10 V, 5…10 V, -10…+10 V, 0…5 V, -5…+5 V, 0…20 mA,4…20 mA. A resolution between 10 and 16 bits is freely selectable.

The converters are designed for harsh environments and have a robust housing made of stainless steel with protection class IP 67 (screwed on). The connections to IO-Link and to the analog port are made conveniently using plug-and-play M12 connection technology. No separate supply voltage connection is required for the converters, as the power is provided by the higher-level IO-Link master via the IO-Link interface.
