Description

This IC697ALG230 module has eight differential inputs and an expansion port. Each input can be individually configured for either voltage or current. Each of the input channels also has individual user scaling. On-board load resistors are included for normal input current ranges up to ±40 mA. If other current ranges or different resolution is required, external resistors may be used. Standard system configurations for ±10 volts and 4 to 20 mA are available. These, and other lower input ranges, can be scaled to engineering units with the user scaling feature.

Applications

Large thermal/nuclear power plants: Acquire signals from turbine pressure, boiler water level, and generator temperature transmitters transmitted over long distances.

Oil and gas plants: Utilize isolation characteristics in explosion-proof instrument interfaces within flammable and explosive areas to prevent the propagation of loop faults.

Iron and steel metallurgical plants: Used in blast furnaces and hot rolling production lines to cope with strong electromagnetic interference generated by the start-up and shutdown of large motors.

Non-ferrous metal electrolysis plants: Acquire current and voltage from electrolytic cells in strong DC magnetic field environments.

Functions

The High Level Analog Input subsystem for the Programmable Logic Controller (PLC) accepts analog inputs of up to ±10 volts full scale, or 4 to 20 milliamp current loop signals. These inputs are converted to digital form for use by the CPU or other controllers accessing analog inputs via the VME backplane. Converted data is presented as 2’s complement (sign + 15 bits). The basic converter is 14 bits resolution (1 part in 16384); an oversampling and averaging technique further enhances this resolution. Inputs are protected against transient and steady-state overvoltage conditions. Analog inputs use %AI references in the programmable controller. A maximum of 8K words of %AI memory is currently available in the programmable controller. Each input channel uses one word (16 bits) of %AI memory.
