This
economical DIN rail or wall mount single phase SCR unit is designed
to control resistive loads, such as heater bands and cartridge heaters,
using the linear 4-20 mA proportional output from a temperature controller.
Using noise-free zero cross
firing,
the robust 7PM comes with a Fast Cycle control option for heavy thermal
loads requiring less frequent switching and a Single Cycle control
option for lighter thermal loads needing faster switching or more
precise control.
