Model MUL270-000 (DC Voltage Multiplier) is designed for industrial applications where the multiplication of DC voltage signals is required. The module has two voltage inputs (X & Y). Each voltage input has an associated Teach terminal that can be used to calibrate the minimum and maximum input levels. In its most basic setup, the module multiplies INPUT X by INPUT Y:
Output=InputX x InputY
A calibrated 100% signal on Input X and on Input Y would nominally produce a full-scale output signal. The multi-turn GAIN and BIAS potentiometers can be used to set the maximum and minimum output levels. Typical output levels are 0-10V, 0-20mA, or 4-20mA.
Input Y also has a TRIM RANGE potentiometer that can be used to limit the minimum range of INPUT Y. This functionality is typically used in the dancer trim and torque takeup/letoff applications. An internal jumper allows selection of a voltage or current output. Onboard EEPROM is used to backup and retain the calibration values during a power loss.
