Cooper Instruments DCM4800-1 Specifications
DCM 4800 - LOAD CELL SUMMING TRANSMITTER
he model DCM 4800 is an AC or DC powered summing
transmitter for up to four load cells with output options of 0-20
T
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 mA 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.
