OUTPUT FUNCTIONS & TYPES (DNT-T103 and DNT-T221 Only)
Regardless of model, any triac outputs are capable of switching up to 24 VAC at a maximum of 0.5 A each, and
may be configured for any of a number of output functions and types. Only the DNT-T221 supports two
0-10v outputs, up to a maximum of 20 mA each. Note that not all applications support all the options listed.
