Supported Applications
The Omega i-Series is a family of microprocessor-based instruments designed for strain and process measurement. The series includes digital panel meters (DPI) and single loop PID controllers (CNI) configured with universal inputs to accept signals from load cells, pressure transducers, and strain gage sensors. These units also support standard temperature and process voltage/current ranges.
Key applications documented for the i-Series include:
- Strain Measurement: Monitoring of load cells, pressure transducers, and strain gages using ratiometric mode.
- Process Control: Heat/cool control, alarm monitoring, and ramp-to-setpoint operations for temperature and process variables.
Operating Conditions & Performance
The i-Series operates within an ambient temperature range of 0 to 55°C (32 to 131°F) with a humidity rating of up to 90% RH non-condensing. The instruments feature front bezel ratings of NEMA 4 (IP65) or NEMA 1/Type 1, depending on the configuration.
Performance specifications for strain and process inputs include:
- Accuracy: ±0.03% rdg ±0.03% range for process and strain measurements.
- Resolution: 10/1 μV for strain/process applications; 1°/0.1° or 10 μV for temperature/process inputs.
- Response Time: 0.7 sec for 99.9% of the final value.
The series supports built-in excitation options including 24 Vdc @ 25 mA, 5 Vdc @ 40 mA, and 10 Vdc @ 60 mA to power connected sensors directly.
Configuration Options
The i-Series is offered in three true DIN sizes: 1/8 (i/8), 1/16 (i/16), and 1/32 (i/32). The series supports a wide range of configurable outputs, communications, and power options to meet specific installation needs.
Output Configurations:
- 0.5 A SSR
- Relay
- DC pulse
- Analog output (Isolated Analog Voltage and Current)
- Ethernet with embedded Web server (-EIT suffix)
- Isolated RS232 and RS485/422 serial communications (-C24, -C4EIT suffixes)
Housing & Display Options:
- Dual display models (DH/DV series) for simultaneous process variable and setpoint viewing.
- Compact depth options (-C suffix).
- NEMA 4 (IP65) front bezel protection available on select sizes.
Power Supply:
- AC Powered: 90 to 240 Vac ±10%, 50 to 400 Hz; or 110 to 375 Vdc equivalent voltage.
- DC Powered (-DC suffix): 12 to 36 Vdc, 24 Vac (or 20 to 36 Vdc for dual display/Ethernet/analog output options).
Special Features:
- Ratiometric mode specifically for strain gages.
- Programmable digital filter.
- Limited alarm versions (-AL suffix) and simplified menu control (-SM suffix).
Key Product Differences
The i-Series distinguishes between standard temperature/process models (CNI series) and strain-specific configurations. Strain gage inputs are identified by the "S" in the model number, such as CNIS32xx or CNIS8xx.
- Model Numbering: The general format is CNI<Size><Model><Suffix>. For example, a 1/32 DIN strain meter with relay outputs might be designated CNIS3244. Strain models (CNIS) are distinct from standard temperature/process controllers.
- Suffix Constraints: The "-SM" simplified menu option is not available on CNIS strain models. Ethernet options (-EIT, -C4EIT) are unavailable for CNI8A, CNI8C, CNI16, CNI16A, and CNI32 controllers.
- Power & Excitation: The "-DC", "-C24", and "-C4EIT" options are not available with built-in excitation. Analog output is incompatible with the "-AL" limit alarm version.
