Temp Range
-10 to +60°C (14 to 140°F)
Maximum Excitation Voltage and estimated Excitation Current
The maximum excitation voltage, on the summing box side of the IS barrier, is 5VDC.
The maximum excitation current is 70mA under normal operating conditions, and is limited to 100mA by the
selected IS barriers.
The required IS barrier supply voltage and actual excitation current drawn for a load cell weighing system,
depends upon the IS barriers selected, the load cell resistance, the cable length between the excitation voltage
source and the summing box, the number of summing boxes, and the number of load cells required for the
weighing system.
Please review the installation section for additional information.
