The AddMe II is a universal LONWORKS I/O node with fully configurable NV (network variable) types. Translation tables allow linearization of type II or type III thermistors or other nonlinear sensors. Both 3k and 10k thermistors can be connected directly to analog inputs. A 24 VDC excitation output is also provided for sourcing up to sixteen 20mA sensor loops.
Network variables for the analog I/O points may be configured for any scalar LONMARK SNVT, fixed point or floating point. In addition, analog inputs may be configured to SNVT_switch with the on threshold programmed via the translation tables.
