ABB Multi-function Controller CPU Module CMC 50-2 H&B Contronic

The ABB Multi-function Controller CPU Module CMC 50-2 H&B Contronic has the following features:

Basic information: model number CMC 50-2, product number P72261-4-9280161, origin is Germany, shipment to the United States of America, Webster, New York, dimensions of about 3.0 inches × 12.0 inches × 7.0 inches, weight of about 2.2 kg.

Functional characteristics: as a multi-function controller CPU module, it is the core component of the control system, can handle a variety of complex control tasks and logic operations, coordinate the operation of various devices in the system.

Performance parameters: CPU is 32-bit and integrated FPU, RAM up to 8Mbyte and buffer and parity, NVRAM has 8Kbyte for storing production and operation data, Flash memory is 2Mbyte for storing operating system and firmware, with a variety of interfaces such as Cnet (O), Cnet (C), Fnet 0, Fnet 1, and Front panel RS422 interface. Front panel RS422 interface to meet different communication and connection needs.

Application areas: Widely used in industrial automation, such as chemical, pharmaceutical, food and beverage and other process control industries, but also for automotive manufacturing, electronics manufacturing and other discrete manufacturing industries, can accurately control the temperature, pressure, flow and other parameters, coordination and control of the production line of a variety of equipment operation and action.

System compatibility: the module belongs to the ABB H&B Contronic and ABB H&B Melody/Contronic S series, with the same series of other modules and equipment with good compatibility, can be easily integrated into the existing ABB control system, to achieve system expansion and upgrading.

The transfer sequence of OTM_C21D can be summarized in following steps: 

• An anomaly occurs on the Line 1 (LN1) 

• Generator start, immediately start generator in case of black-out, phase-loss, overvoltage or undervoltage (If Generator mode is selected) 

• The Line 2 start the normal functioning,  transfer delay Ts 

• Change-over switch (Switch I) to the position 0 

• Change-over switch (Switch II) to the  position II

And the return sequence can be summarized in  the following steps: 

• The Line 1 will start the normal functioning 

• Change-over switch stays in position II 

• An anomaly occurs on the Line 2 (LN2) 

• Change-over switch stays in position II 

• Change-over switch can be transferred  manually back to position I
