About us
Description
The MC80 PLC's HSC IO function is connected using the 28-pin terminal block (BMXFTB28x0).
DANGER
HAZARD OF ELECTRIC SHOCK
  • Disconnect voltage supplying sensors and pre-actuators before plugging/unplugging the terminal block on the module.
  • Remove the terminal block before plugging/unplugging the module on the rack.
Failure to follow these instructions will result in death or serious injury.
