What is the maximum device capacity of the 4100ES, and how does IDNet loop expansion work?

The 4100 series supports a maximum capacity of 2,000 points, which can be a mix of conventional and addressable input and output circuits [1].

A single system consists of one CPU card and up to 119 addressable expansion cards [1].

For large-scale applications, up to 99 panels or nodes can be networked together [1].

IDNet loop expansion is achieved through the following methods:

1. Adding Expansion Cards: Technicians can add dedicated IDNet option cards or other addressable expansion cards to the system cabinets, up to the 119-card limit per CPU [1].

2. Power Supply Integration: IDNet points can be hosted directly on a System Power Supply (SPS) [1].

3. Remote Units: The system supports up to 31 remote units (such as remote LCDs or I/O modules) via a Remote Unit Interface (RUI), with up to 4 RUI loops available per CPU [1].

4. Loop Loading: Each IDNet line supports up to 250 devices at a distance of 2,500 feet, or 127 devices at a distance of 4,000 feet (Page 176) [1].
