Signal Conditioners, Process Transmitters, and Converters

Process signal conditioners and process transmitters isolate, filter, amplify, and convert sensor signals to 4-20mA current or 0-10V signals for interfacing with controllers and other instrumentation. Select from 2-wire loop-powered 4-20mA transmitters, or 4-wire AC/DC-powered transmitters. Acromag offers 3- and 4-wire models with 4-20mA transmitters or voltage transmitters. DIN-rail and field-mount versions are available. Process transmitter configuration is easy with Windows® software, pushbuttons, switches, or pots for span/zero settings, depending on the series.

    611T, 612T: Single or Dual Channel, DC Voltage/Current Input, DC-Powered Transmitters

    • ±100V DC, 0 to 100mA DC, 0 to 20A AC (with optional sensor) input
    • 0 to 20mA, 0 to 10V DC output
    • 10-36V DC power
    • Universal DC I/O transmitters with auto-configuration and self-ranging capabilities
    These units receive DC current or voltage input signals, provide isolation, and output proportional DC current or voltage signals. With support for universal DC I/O ranges, 610T series transmitters provide a solution for a wide variety of isolation and signal conversion tasks. The single-channel 611T and dual-channel 612T are ideal for panel shops and end-users who require a high-density signal conditioner that can accommodate a broad range of instrumentation applications

Signal Conditioners, Transmitters and Converters Continued

Acromag high-performance signal conditioner products include process transmitters4-20mA signal isolatorslimit alarmssignal splitters, and math computation modules. These products isolate, amplify, filter, condition, and convert measured signals from sensors and other instruments. The enhanced signal is ready for interfacing to your PLC, DCS, display, recorder, or other process control instrumentation.

Temperature transmitters convert thermocouple, RTD, and low-level temperature sensor signals to 4-20mA, 0-10V, or other DC voltage/current outputs. Acromag offers temperature transmitters in head-mount and DIN-rail form factors. Some temperature transmitters have software-configured universal input to convert a broad range of temperature sensor and other signals with a single unit.
