    841T: DC Frequency/Pulse Input Intelligent Transmitter

    • 0 to 50KHz, 0 to 65535 pulses input
    • 0 to 20mA DC, 0 to 10V DC output
    • Mechanical alarm relay (25V @ 5A)
    • 10-36V DC power
    • Software configured; pulse counter; signal averaging; optional limit alarm functions
    These transmitters isolate and convert sensor inputs to noise-free, proportional DC current or voltage output signals. An optional relay output adds a local limit alarm function.
