Supported Applications

The Omega CNI-CB120SB series is a Temperature and Process On/Off or PID Digital Controller Panel designed for light industrial use. The unit provides temperature measurement and control, featuring factory configuration and calibration for thermocouple inputs while supporting RTD, voltage, or current signals via M-12 female connections.

Documented applications include:

Temperature measurement and control
Process control with On/Off, PID, and Ramp/Soak functions
Indoor, general-purpose use in dry environments only (not NEMA rated)

The series is not designed for human, medical, nuclear, or other safety-critical applications.

Operating Conditions & Performance

The CNI-CB120SB operates within an ambient temperature range of 0 to 55°C (32 to 151°F). The unit is powered by a 120V supply and housed in a hinged metal enclosure. Dimensions are specified as 203 H x 152 W x 152 mm D (8 x 6 x 6") with a weight of 4.53 kg (10 lb).

Electrical output capabilities depend on the configuration:

If using both outputs simultaneously, the maximum rated current for each output is 6.0A; each output must be fused for 7Amps (720Watts).
If using only one output, the maximum rated current is 12.0A; the output must be fused for 15Amps (1440Watts).

When both outputs are used, the combined maximum output is limited to 15 A due to a 15 A maximum input constraint.

Voltage and Signal Outputs

Two controlled output relays (up to 15 A total)
Analog outputs: 0 to 1V, 0 to 10V, or 4 to 20 mA

Configuration Options

The series supports multiple sensor input types and communication options. The base model includes a Type K thermocouple input with an M-12 female connection for RTD or process signals.

Sensor Inputs: Configurable for Thermocouples (Type J, T, E, N, R, S) by changing the suffix in the model number; factory configured and calibrated for Type K unless otherwise specified. Also supports RTD, Voltage, or Current inputs.
Housing: Hinged metal enclosure with main power light and output indicator lights.
Communication Options: Optional Ethernet control with a built-in web server (indicated by the "-EI" suffix).

Ordering Configuration Examples

CNI-CB120SB-K: Temperature/process single input controller with dual outputs.
CNI-CB120SB-K-EI: Temperature/process single input controller with dual outputs and Ethernet web server.
Option M12-S-M-FM: M-12 field mountable 4-pin connector with terminal lugs for wire connection.

Fuse Configuration

The unit comes complete with a CNI16D33 controller, one 1 A control fuse, one 15 A output fuse, and two fuses rated at 5 A and 10 A respectively.

Key Product Differences

Variants in the series are distinguished by sensor type suffixes (e.g., -J, -T, -E, -N, -R, -S) to match specific thermocouple inputs. The "-EI" designation indicates models equipped with an Ethernet web server for remote control.
