Specifications

Descripution

The 1756-DMD30 Allen-Bradley ControlLogix drive module is a single-slot industrial ControlLogix module which enables device interfacing with the Reliance Electric Distributed Power System (DPS) equipment. Each 1756-DMD30 module interfaces with an individual Power Module Interface (PMI) chassis and it performs torque, position, and velocity control. The 1756-DMD30 module works with SD3000 6 Pulse DPS equipment system which is an S6 DC drive and an S6R resolver and with the SD3000 12-Pulse equipment system which is a S12 DC drive and S12R resolver.

The 1756-DMD30 module is installed inside a ControlLogix chassis and it communicates to the SynchLink nodes through a fiber optic network. The 1756-DMD30 module also connects to PMI chassis through fiber optic cables. The 1756-DMD30 module is a single-slot module and it operates on DC power that is supplied by the ControlLogix chassis. The module current consumption rating at 24 Volts DC is 3 milliamps and at 5.1 Volts DC, it is 1.35 Amps.

The peak power dissipation is 6.96 Watts and the thermal dissipation is 23.7 BTU/hr. Green and red indicators are provided on the module for diagnostics, status, and operation updates. The storage and operating temperature ranges are -40 to 185°F and 32 to 140°F, respectively. The operating shock rating is 30 G. The recommended ambient relative humidity range is 5 to 95%. The MTBF (Mean Time Between Failure) is 1.7 million hours.
