Product Name(s):
IOM/2
Product Description:
IOM/2 is a general purpose, programmable 16 I/O (expandable to maximum 40 I/O), secondary controller intended for general on/off or modulating control of mechanical and electrical systems. Requires communications support from Savvy or Executive Processor (EP) primary control units.
Product Application(s):
The IOM/2 can be programmed for custom control of building mechanical and electrical systems, including heating and cooling plants, AHUs, packaged equipment, lighting and power panels.
