  • 5 Universal Inputs (0-5V, 0-10V, 0-20 mA, thermistor, dry contact or open-collector)
  • 7 Digital Inputs (dry contact or open-collector)
  • 4 Analog Outputs (0-10V)
  • 7 Digital Outputs (relay N.O.)

The Smart I/O™ EC230 programmable controller incorporates 23 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 EC230 has expanded data storage with additional FLASH, SRAM and EEPROM memory. The EC230 can be utilized in many custom or fixed distributed control applications.

The I/O of the EC230 makes it perfect for a variety of equipment control applications. The wide operating temperature range, -20 to 70 °C, makes the EC230 well suited for many demanding applications.

The cost effective I/O allows numerous applications to be development and implemented with the EC230. The Real Time Clock and expanded memory allow applications for data logging, scheduling and time stamp monitoring and control. A factory default application is provided with each EC230 to monitor inputs and control outputs. User defined algorithms and functions can be programmed using VisualControlÔ, NodeBuilder, LonBuilder or other third party LONWORKS programming tools. The custom application programs can be downloaded over the free topology network and is stored in non-volatile memory to retain applications and data even after loss of power.

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