GE PRG-MODEM Timer card

The DC power source is connected to the MMC system through a 3-pin connector. It plugs into the power connector of the MMC. The ground from the power source and ground from the MMC must be connected to the Single-Point Ground (SPG). Devices connected to the hardware may have their own power sources for input data or output control signals. You can use other wiring setups, provided that each one is: • at the correct voltage and current levels for the module and the device. • connected to the same Single-Point Ground that the MMC uses. It is recommended that the same main disconnect switch be used for the MMC system and for all devices in the application.

Notes on the 24V power supply and the MMC 

An MMC system consists of a main module (servo analog or SERCOS based) and up to two option modules. An external 24 VDC supply is required to power the MMC’s internal circuitry and external I/O. The 24 VDC is distributed internally to three different buses or sections. When you size your power supply, you must ensure that the supply is large enough to handle the total load and that the maximum current capability of each bus is not exceeded.
