Question

There are several Echoflex contact interfaces; what are the differences between them?

Explanation

Echoflex Contact Output Interface (ERCOI)

  • Allows Echoflex controls (switches/sensors) to trigger a contact for integration with third-party systems.
  • Echoflex output device (hint: LEARN button)
  • Controlled by Echoflex switches and sensors
  • Configure interface channels as Echoflex outputs
  • 4 independent dry contact channels
    • Each channel has normally open (NO), normally closed (NC), and common (COM) terminals
  • Power source: 8-30VDC or 24VAC, 250mA max draw

Echoflex Contact Input Interface (ERCII)

  • Allows third-party contact output devices to control Echoflex outputs (controllers)
  • Echoflex control device (hint: TEACH button)
  • Wirelessly link to Echoflex controllers
  • Configure interface channels as Echoflex controls (including which type of station/sensor they behave as)
  • 4 independent dry contact channels
    • Each channel has 5VDC and IN terminals
  • Power source: 8-30VDC or 24VAC, 250mA max draw

Echoflex Universal Input/Output Interface (UIO)

  • Blend of both the ERCOI and ERCII functionality
    • 2 independent output channels, 2 independent input channels
  • Outputs
    • Wirelessly link to Echoflex controllers
    • Configure interface channels as output devices
  • Inputs
    • Wirelessly link to Echoflex outputs
    • Configure interface channels as control devices, including custom commands
  • Each contact channel supports 0-10VDC (dimmed) or 4-20mA (contact).
    • These can be either wet (supplying valtage) or dry (receiving voltage) based on placement of a jumper.
  • Power source: 9-24VDC or 24VAC, 200mA max draw
