The HD480-I Heater Driver is an upgrade/conversion option for the godet heater driver on Rieter extrusion machinery. The unit mounts in place of the original heater driver but accepts a standard 4-20 mA signal (instead of the 14,935 - 21,731 Hz Rieter frequency signal) for 0 - 300° C sensed temperature. When used in conjunction with the Binsfeld DS220 Digital Stator, the HD480-I allows users to convert machine control from the unique Rieter frequency to industry standard 4-20 mA.
Soft-Start - at the beginning of every PWM period to extend heater life
User Selectable Ramp Time - soft-start ramp time from 0 to 18 AC half-cycles
User Selectable PWM - PWM period from 1.0 to 2.8 seconds
No External DC Power Required- powered from 4 - 20 mA input
