Mixed modules support a combination of electrical types, such as universal inputs mixed with digital or analog outputs. The available mixed modules include the following:

  • UI-8/DO-FC-4 and UI-8/DO-FC-4-H

  • UI-8/AO-4 and UI-8/AO-4-H

  • UI-8/AO-V-4 and UI-8/AO-V-4-H

Note:

Module names with an -H indicate the presence of Hand-Off-Auto override switches.

UI-8/DO-FC-4 and UI-8/DO-FC-4-H Central IO Modules

These Central IO modules combine 8 universal inputs and 4 digital outputs of the Form C relay type. You can use these modules when an application requires only a few I/O points of each type. The universal inputs can be used for any mix of temperature, pressure, flow, status points, and similar inputs. The Form C relays are designed for direct load applications for up to 3 A loads.

For more information, see UI-8/DO-FC-4 and UI-8/DO-FC-4-H Central IO Modules .

UI-8/AO-4 and UI-8/AO-4-H Central IO Modules

These Central IO modules combine 8 universal inputs and 4 analog outputs. You can use these modules when an application requires only a few I/O points of each type. The universal inputs can be used for any mix of temperature, pressure, flow, status points, and similar inputs. The analog outputs can be used to control a wide range of devices, such as valves and actuators, using a 0-10 VDC or 0-20 mA control signal.
