37
A compact, freely programmable controller which is LonMark
®
certified and
has 20 fixed inputs and outputs. The controller can be expanded to up to 40
inputs/outputs using two expansion modules. It does not include peer-to-
peer or BMS communication. The controller can be upgraded at any time to
a networkable version without changing the hardware. The TAC Xenta OP
Operator Panel and a compatible terminal block are included in the stand-
alone package.
