EC240

12 Universal Inputs (0-5V, 0-10V, 0-20 mA, thermistor, dry contact or open-collector)
6 Universal Outputs (0-10V or Triac)
6 Digital Outputs (Triac)

The Smart I/O™ EC240 programmable controller incorporates 24 channels of cost effective analog and digital I/O with a real time clock. The I/O is monitored and controlled by a Neuron 3150 chip with Free Topology communication over a LonWorks^® network. The EC240 has expanded data storage with additional FLASH, SRAM and EEPROM memory. The EC240 can be utilized in many custom or fixed distributed control applications. The I/O of the EC240 makes it perfect for a variety of equipment control applications. The wide operating temperature range, -20 to 70 °C, makes the EC240 well suited for many demanding applications.

The twelve universal inputs (UI) can be configured in a variety of ways. The controller can interface with resistive type sensors for temperature measurements. The UI’s can measure voltage from humidity or transducer readings. The UI’s can input current for pressure measurements. The UI’s can also be used to read digital inputs and dry contacts. With 12 bits of resolution, the universal inputs are field adaptable and accurate for many types of measurements.

The EC240 controller is protected from reverse power supply input wiring, over-voltages, transients, and other common events that can damage unprotected inputs and outputs. The versatile I/O allows numerous applications to be development and implemented with the EC240. The Real Time Clock and expanded memory allow applications for data logging, scheduling and time stamp monitoring and control.

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 free topology network and is stored in non-volatile memory so it is retained even after loss of power.

The enclosure snaps right onto a 35mm DIN-rail for quick and easy mounting. Its spring-loaded latching mechanism makes it easy to remove.
