Technical Specifications

The IISAC01 is a panel-mounted, single-loop process monitoring and control interface that communicates directly with central control modules (such as the IMMFP11/12 Multi-Function Processors) via an expansion bus or termination unit.

  • Display Configurations:

    • 3 Gas Plasma Bar Graphs: 200 segments for Process Variable (PV) and Setpoint (SP) at 0.5% resolution; 100 segments for Output (OUT) at 1.0% resolution.

    • 8-character, 14-segment alphanumeric character display for real-time data readings and tag alerts.

  • Input Parameters: Accepts voltage inputs ranging from +0.75 VDC to +5.25 VDC with an 8-bit A/D resolution. Features a built-in square root function option for flow calculation variables.

  • Output Parameters: Delivers a current output range of 3 to 21 mA with an 8-bit D/A resolution. Supports load compliance up to 600 ohms.

  • Communication: Standard RS-485 serial link operating at either 5 kbaud or 40 kbaud.

  • Power Supply: Operating voltage of 21.6 VDC minimum to 27.0 VDC maximum, pulling 540 mA at 24 VDC.

  • Mounting & Form Factor: Flush panel mounting; physical dimensions measure 72 x 144 x 381 mm (2.82 x 5.67 x 15.0 inches).

Target Industries

  • Power Generation: Deployed heavily in fossil fuel, gas turbine, and steam generation plants for manual/automatic station loop overrides.

  • Chemical and Petrochemical: Used in critical process refineries to monitor heating mantles, distillation stages, and pressure vessels.

  • Pulp and Paper: Installed on operational floors near digesters and paper machines to give technicians localized loop visibility.

  • Water Utilities: Used in water purification, desalination, and major municipal pumping stations.

Application Scenarios

  • Manual/Automatic (M/A) Loop Switching: Provides control-room operators or field technicians with direct faceplate access to switch critical PID loops from automated DCS control to manual control.

  • Setpoint Manipulation: Allowing on-the-fly local adjustments to the process target variables (Setpoint) directly from the panel.

  • Critical Flow Visualizing: Monitoring input channels running square root calculations from differential pressure transmitters to show clear volumetric flow rates.

  • Backup Control Stations: Acting as a hard-wired failsafe fallback interface if the higher-level console architecture or HMI software goes offline.
