Functional Description

DS200TCQEP2AAB is a Software EPROM developed by GE under the Mark V control system. Electrically erasable programmable read-only memory (EEPROM) permanently stores up-to-date application software and configuration settings. EEPROM ensures that any changes made to the system, such as sequencing modifications, I/O assignments, and gain adjustments, are retained even after a power cycle.

Contact Inputs

• The Mark V control system uses a sophisticated contact input mechanism to monitor and process external signals, ensuring precise control and response to various field inputs. This system is designed to provide high reliability and flexibility, offering the ability to interface with a wide range of input voltages, making it adaptable to different operational needs.
• At the core of the Mark V’s contact input system is the 125 V DC bus, which is sourced from the internal power distribution core. This bus is utilized to generate an interrogation voltage that is both fuse-isolated and current-limited, ensuring a safe and stable connection to the external contact inputs. This voltage allows the system to accurately read and interpret the signals from connected devices while preventing potential damage to the system components from overcurrent or faults.
• Although the 125 V DC bus is the standard interrogation voltage, the Mark V control system can accommodate a range of other input voltages, typically between 24 V DC and 125 V DC. For input voltages outside the default range or when a specific voltage source is required, the Mark V can integrate external power sources. This capability enhances the system’s versatility, allowing it to interface with a variety of field devices, such as switches, sensors, and other monitoring equipment, that may operate at different voltage levels.
• One of the key features of the Mark V contact input system is its ability to isolate field grounds to prevent interference or unwanted electrical noise. Jumpers on the terminal boards can be employed to disconnect the interrogation voltage from the contact inputs in groups of eight. This functionality is critical for isolating certain groups of inputs, ensuring that issues with one set of inputs do not affect the operation of others. It also allows for easier maintenance and troubleshooting, as the system can be adjusted to isolate specific areas of the input circuitry when necessary.
