The model DCM 4800 is an AC or DC powered summing transmitter for up to four load cells with output options of 0-20 mA, 4 to 20 mA or 0-10 Vdc. All input/output options are included on the board so there is no need to specify input/output parameters with the DCM 4800. The DCM 4800 has a built-in excitation supply capable of delivering up to 120 m A at 10 Vdc. The DCM 4800 offers three way isolation, input to output and power, eliminating unwanted ground loop problems. Overall accuracy over the normal room temperature range is excellent at <+0.1 %. Designed with large tare offset requirements in mind, the DCM 4800 can tare off up to 80% of the output of a 3 mv/v load cell at 10 Vdc excitation. If high/low setpoint, alarms/controls are desired, the DCM 4800 board is laid out to accept Opto-22 output relays. Potentiometers are accessible to adjust the high and low trip points.
