841T: DC Frequency/Pulse Input Intelligent Transmitter
Product short description:
- 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
841T Intelligent Transmitter with DC Frequency / Pulse Input Description
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.
Each unit offers a selection of input and output ranges, as well as several signal conditioning options. This flexibility enables a single IntelliPack to handle a broad range of applications. As your needs change, you can easily reconfigure the unit for different ranges or functions.
Setup is very easy. IntelliPack modules are quickly configured with the user-friendly Windows software program. Field adjustments are simple with the module’s front-panel push-buttons and status LEDs. Once configured, IntelliPacks operate independent of any host computer.
