PS-1040/45 digital/analog transmitters provide signal conditioning, amplification, and a corresponding digital or isolated analog output signal for tank/bin/hopper weighing systems. Front panel configuration and calibration streamlines system installation and operation. Calibration and configuration parameters also can be downloaded via PC based Pro-View Software. In either case, no dip switch or potentiometer adjustments are required. Calibration options accommodate front panel data entry or dead load weighing methods. High level serial communication is available in RS-232, RS-422, or RS-485 format with Modbus RTU protocol. Up to 32 transmitters can be connected point-to-point using the RS-485 serial output. BLH offers the PS-121, 24Vdc Power Supply (data sheet #12155), for PS-1040/45 operations. NOTE: Model PS-1040 requires Pro-View Software for calibration and system parameter entries
