Product Description
The EasyIO FC-20 is the first product in the FC-range, designed to complement the EasyIO 30P and FG-series of awarding winning excellence. All of the FC-series products are equipped with two RS485 ports and no Ethernet port, for Ethernet applications you can upscale to the EasyIO 30P or FG-series. All FC products are BACnet and Modbus selectable and can be programmed via the CPT Tool.
The EasyIO FC-20 has 20 I/O and priced to meet the most high volume applications and price points. The new EasyIO FC-20 is a microprocessor based controller consisting of 20 inputs/outputs (I/O) to accommodate general and specific applications featuring BACnet MSTP and Modbus RTU communication protocols. 20 I/O includes 12 Universal inputs (UI) supporting current, voltage and resistance based sensor. 4 electrically isolated Digital Outputs (DO) and 4 analog inputs supporting current and voltage outputs.
The EasyIO FC-20 comes with one standard RS485 driver to support either BACnet MSTP or Modbus RTU communication (selection via hardware dip-switch). This communication port is also used as configuration/setting and firmware upgrade.
Specifications
– ARM Cortex-M3, 24MHz processor
DEVICE INPUTS & OUTPUTS
– 12x Universal inputs
– 4x Digital outputs with LED for status
– 4x Analog outputs (200mA sink for switching relays)
COMMUNICATION
– 1x RS485 port for Modbus RTU and BACnet MSTP
– 1x RS485 port for Modbus RTU (for Application Specific Application only)
INPUT/OUTPUT CONTROLLER
The concept behind the FC-series is that the EasyIO FC-20 can be used as an input/output controller only, or an Application Specific Controller. There is also a Real-time clock and a second RS485 (reserved for communicating with other Modbus devices such as Power Meters) port provided for such application.
