As of Nov 26th, 2018, ICN77000 Micro-Infinity Series will be discontinued. For the last time buy please contact Sales for details. As a possible substitute, please check out the PT Controller for details.

The MICRO-INFINITY® controllers offer unparalleled flexibility in process control. Each unit allows the user to select the input type, from 10 thermocouple types (J, K, T, E, R, S, B, C, N and J DIN), Pt RTDs (100, 200, 500 or 1000ohm, with either 385 or 392 curve), or analog voltage or current input. The voltage/current inputs are fully scalable to engineering units, with selectable decimal point, perfect for use with pressure, flow or other process input.
"R" Series - For easy-to-drill round holes
The MICRO-INFINITY® controller features a large, dual LED display, front panel configuration, selectable Temperature/process inputs and universal power supply that accepts 90 to 250 Vac or Vdc. Available in single and dual output configurations, the ICN77000 Series is available with relay, SSR, dc pulse, analog voltage or current outputs. A single alarm is standard. Options include a second alarm, RS-232, RS-485, analog output or remote setpoint selection.

The "ICN77300" series controllers have many features of larger, 1/4 DIN controllers in a compact, 1/16 DIN size. These controllers feature a 1/16 DIN cutout and bezel with a NEMA 12 rating, dual LED displays, with different colors for the actual process and setpoint values. Individual indicators provide output and alarm status.

The "ICN77500" features a 1/16 DIN cutout, 53.3 mm (2.1") square face with NEMA 4 rating, large dual LED display, front panel configuration, and selectable Temperature/process inputs. Available in single and dual output configurations, the ICN77500 is available with relay, SSR, dc pulse, analog voltage or current outputs. A single alarm is standard.

The ICN77R300 and ICN77R500 controllers feature a unique detachable display and adapter with a NEMA 1 rating to allow mounting in a round, 1.75" cutout. This feature allows users to prepare the panel with a standard round hole saw. The 2-piece design snaps together, for quick easy installation.
