It supports rated applied voltages from 24 to 125 V DC and 100 to 240 V AC at 50\/60 Hz. Its configurable output fallback functions allow the module to hold existing output states, switch all channels off, or perform no fallback action when the specified trigger occurs.\u003c\/p\u003e\n\u003ch3\u003eOutput Channels and Load Ratings\u003c\/h3\u003e\n\u003cp\u003eThe module provides 16 output channels for controlling external loads.

The maximum current per common is 8 A, so the combined load on each eight-channel common must remain within this limit, even when individual channel ratings are higher.\u003c\/p\u003e\n\u003cp\u003eQ: Can the HOLD and OFF fallback modes be configured separately for different channels?\u003c\/p\u003e\n\u003cp\u003eA: No. The selected fallback behavior applies commonly to all output channels.
