CN77533 NEMA 4 square cutout.
The high-accuracy, high-quality MICROMEGA® 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, 500, or 1000 Ω, with either 385 or 392 curve), or analog voltage or current input. The voltage/ current inputs are fully scalable to engineering units, with a selectable decimal point, perfect for use with
pressure, flow, or other process inputs.
The MICROMEGA® 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 singleand dualoutput configurations, the CN77000

CN77000 R300 and R500 controllers shown with model RHS-43 hole saw for easy-to-drill round holes. See last page for ordering information.
CN77333-A2 NEMA 12 style square cutout.
Series is available with relay, SSR, DC pulse, or analog voltage or current outputs. A single alarm is standard. Options include a second alarm, RS232, RS485, analog output, and remote setpoint selection.
The “300” Series controllers offer 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 (IP54) rating, and dual LED displays, which show different colors for the process and setpoint values. Individual indicators provide output and
alarm status.
The “500” features a 1⁄16 DIN cutout, 53.3 mm (2.1") square face with NEMA 4 (IP65) rating, large dual LED display, front-panel configuration, and selectable temperature/process inputs. Available in singleand dual-output configurations, the
CN77500 is available with relay, SSR, DC pulse, or analog voltage or current outputs. A single alarm is standard.
The R300 and R500 controllers feature a detachable display and adaptor to allow mounting in a round, 44 mm (1.75") cutout. This feature allows users to prepare the panel with a standard round hole saw as well as the conventional 1⁄16 DIN cutout.The 2 piece design snaps together, for quick, easy installation.
