  • 0-2.0″ W.C. precision air flow sensor
  • 4 Universal Inputs (0-5V, dry contact or thermistor)
  • 1 Analog Input (0-5V, 0-10V)
  • 5 Digital Outputs (Triac)

The Smart I/O™ EC100XP is a fully programmable controller allowing a complete sequence of operation customization for today’s ever-changing control strategies that are required to meet continued energy efficiency requirements. The reliable cost effective I/O is continuously monitored and precisely controlled by a microprocessor for exceptional performance. To eliminate memory constraints caused by today’s complex applications an additional 8K of external SRAM has been added to the existing memory architecture of the EC100XP. A precision airflow sensor provides reliable and accurate measurements allowing superior performance. Communication for monitoring, control and diagnostics is achieved utilizing a LonTalk® TP/FT-10 network with a simple twisted-pair, un-polarized cable.

The five universal inputs (UI) can be configured in a variety of ways. Universal inputs 1 through 4 (UI1-UI4) can interface with resistive type sensors for temperature measurements. These four inputs can also measure 0-5 volts from typical low output resistance sensors. Universal inputs 1 through 4 are also well suited for reading digital inputs and dry contacts for status or alarm conditions. Universal input 5 (UI5) is specifically set-up to measure only voltage. The default voltage range is 0-5 volts and can be set to measure 0-10 volts with the change of an option jumper. The UI’s are well suited to measure voltage values from humidity and many other transducer output signals. With 12-bits of resolution, the universal inputs are field adaptable and accurate for many types of measurements. The five digital outputs (DO) are Triac outputs for control of additional on/off or pulsed external devices where the current does not exceed 1A at 24 VAC. The EC100XP controller is protected from reverse power supply input wiring, over-voltages, transients, and other common events that can damage unprotected inputs and outputs.

User defined algorithms and functions can be programmed using VisualControl™, NodeBuilder, LonBuilder or other third party LONWORKS programming tools. The application program can be downloaded over the LonTalk network and is stored in nonvolatile memory allowing the application to be retained even after loss of power. The versatile I/O allows numerous applications to be development and implemented with the EC100XP.

The enclosure snaps securely onto a 35mm DIN-rail for quick and easy mounting. A spring-loaded locking clip allows for quick and easy removal. The wide operating temperature range, -20 to 70 °C, makes the EC100XP well suited for many demanding applications.
