The BIALON DK-10DI supports the acquisition of 10 digital inputs on LONWORKS Power Line or Free Topology networks. Thanks to electrically isolated inputs, both switches and buttons can be evaluated via software. An external power supply is required for potential isolation. Alternatively, the module provides a 12 V output voltage (no potential isolation). The acquired inputs signals are available on the entire LONWORKS® network as SNVT_switch and SNVT_lev_disc. The state of each digital input is visualised by an LED. All software objects are programmed as per the LONMARK® standard. An LNS plugin is available on the STV website for configuring the BIALON DK-10DI.
