Supported Applications

The Omega CNiS8/DPiS8 Series comprises 1/8 DIN high-accuracy strain process controllers and meters designed to measure DC voltage and current inputs from load cells, pressure transducers, and strain gauge type of transducers. The series includes two primary instrument configurations: the DPiS8/CNiS8 models for Strain/Process monitoring with optional control outputs, and limit alarm versions designated by the -AL suffix which provide an Alarm Menu without PID Control.

Operating Conditions & Performance

The series supports universal power supply options including 90 to 240 Vac/dc at 50-400 Hz (standard) or low voltage configurations of 12 to 36 Vdc for CN/DPi8 models, 20 to 36 Vdc for CN/DPi8A models, and 24 Vac. Built-in excitation is available as selectable 5V @ 40 mA or 10V @ 60 mA; however, this feature is not available with optional isolated RS-232/485 serial communication options (-C24) or the -DC power supply option.

Performance specifications for temperature inputs (available on related iSeries models within the family documentation context but distinct from the Strain-specific DPiS8/CNiS8 focus in this series title) include accuracy values such as 0.1°C / 0.2°F for RTD-1N Nickel MIL-T-7990B inputs and 0.4°C / 0.7°F for standard Pt, 0.00385 RTDs across ranges like -200 to 900°C (-328 to 1652°F). The instruments feature a large, three-color programmable display that changes color when an alarm is triggered.

Configuration Options

The series offers configurable control and communication outputs tailored for process monitoring or limit alarming:

  • Control Outputs (CNiS8): Options include two solid state relays (SSR's) at 0.5 A @ 120/240 Vac continuous; combinations of SSR and Form "C" SPDT relay rated 3 A @ 120 Vac, 3 A @ 240 Vac; or pulsed 10 Vdc @ 20 mA for use with external SSRs.
  • Analog Outputs: Selectable as control or retransmission of process value (Option 5), providing 0 to 10 Vdc or 0-20 mA @ 500 ohm max. Note that Analog Output is not available with -AL units.
  • Communication Options: Programmable RS-232/RS-485 (-C24), Ethernet with Embedded Internet (-EI), or Ethernet with Embedded Web Server plus isolated RS485/422 hub for up to 31 devices (-C4EI).
  • Housing and Display: The unit features a removable front panel. Factory setup options include scaling for MIL-T-7990B Nickel RTD inputs (0 to 200°C or -40 to 300°C) via the -FS suffix.

Key Product Differences

The series distinguishes between monitor-only and controller configurations. The DPiS8 model is a Strain/Process Monitor only, while the CNiS8 includes two control outputs. Specific variations include:

  • -AL Suffix: Designates Limit Alarm Version with an Alarm Menu but no PID Control.
  • -SM Suffix: Simplified Menu Version providing ON/OFF Control without PID; note that Strain CN/DPiS8 and Isolated Analog Output models are not available with -SM units.
  • Analog Output Constraints: The DPi8A/CNi8A variants offer isolated analog output, but this option is incompatible with Ethernet options (-EI/-C4EI) for the CN/DPi8A family. Additionally, Analog Output (Option 5) and -AL units are mutually exclusive.
