Honeywell XL100C DDC controller, 12 universal inputs, 12 universal outputs, 12 digital inputs.

The Excel 100C Controller is a direct-digital control, microprocessor-based, programmable controller for managing
building functions.

The Excel 100C monitors and commands HVAC equipment controls for buildings (industrial, retail, hotel, school, health
care buildings, etc.). It can operate as a stand-alone unit or as an integral part of a higher-order system.

The Excel 100C easily accommodates expansion via a sophisticated peer-to-peer Communication Bus (C-Bus). Up
to 30 devices ─ such as Excel Building Supervisors (XBS), other controllers, interfaces to 3rd part systems etc. ─ can be
connected to the C-Bus. Long-distance communication to a remote XBS is supported via modem or ISDN.

The Excel 100C is easily handled using the XI582 Operator Terminal (supports bus-wide access) or the PC-based XLOnline tool for easy start-up of the controller (e.g. downloading applications, implementing on-site adjustments, etc.).

A PC-based Excel Building Supervisor workstation provides a graphic operator interface for managing a network of
controllers.

Control applications are generated using CARE, a PC-based graphic tool which simplifies the engineering process. Once
the control applications have been engineered, they can be simulated and adjusted in CARE, which also assists in the
startup and troubleshooting of the application programs.
