9244

Din rail mount load cell transmitter DC supply

The Model 9004/9244 is a miniature space saving 92 x 92 x 26mm DIN-rail mount programmable load cell transmitter. Configuration and field calibration is done via a notebook or desktop PC using the userfriendly software available from our web site. Complete 3-way isolation is provided between power supply, input and output.

The transmitter is designed for mV inputs from load cells, strain gauges and strain gauge pressure transmitters. The stable bridge excitation voltage is user selectable for normal or Intrinsically Safe applications, and can power four load cells with the standard 10V excitation. Sense feedback is included to compensate for cable loss. The precision instrumentation op-amp front end circuit ensures high accuracy and stability. The digital filter feature allows for a stable output in noisy systems. The isolated analogue output is configurable for industry standard 0-10V or 0-20 / 4-20mA signals. The power supply is 95-265V AC/DC as standard for the model 9004 and 10-30V DC as standard for the model 9244. The RS 232 serial interface and a remote tare function is standard.

The serial interface allows connections to remote computers and SCADA systems using DPM’s DIGIbus protocol. The RS 485 option allows up to 99 transmitters to be linked on the same bus.

A feature of this programmable transmitter is the calibration method. Pre-calibrated ranges can be allocated zero and full scale values and these can be adjusted on site via a notebook to allow for dead-weight offset and a single point span calibration (test weight trim).
