ABB Termination Plug PZ 754 H&B Contronic
Functional Characteristics
Accurate termination of signal: The main function is to accurately terminate the signal transmission in the electrical circuit to ensure that the signal stops at the predetermined position, avoiding signal reflection, crosstalk or interference with other lines and equipment, and guaranteeing the accuracy and stability of the system signal transmission.
Reliable connection performance: with good connection performance, it can closely match with the corresponding socket or interface to ensure a firm and reliable connection between the plug and socket, and even under severe environmental conditions such as vibration, shock and temperature change, it can also ensure the continuity of the electrical connection to prevent the signal interruption or poor contact due to the loosening of the connection.
Electrical isolation protection: It plays the role of isolating different circuits or equipments in the electrical system, preventing the propagation of electrical faults in the system, improving the safety and reliability of the system, and at the same time, it can also protect the personnel and equipments from potential electrical hazards.
Technical Parameters
Rated Voltage: Usually can withstand about 250V AC or other voltage levels suitable for industrial control, in order to meet the electrical safety requirements of different application scenarios.
Rated current: the rated current is generally between a few amps and a dozen amps, common 10A, etc., according to the actual load conditions to choose the right model, to ensure that no overheating, damage and other problems due to overloading during normal operation.
Contact resistance: the contact resistance is very small, generally in the milliohm level or even lower, in order to reduce the loss and heat in the signal transmission process, to ensure the efficiency and quality of signal transmission.
Insulation Resistance: High insulation resistance, usually above megohm level, such as 1000MΩ or more, to ensure good electrical insulation performance and prevent leakage, short circuit and other faults.
Application Scenario
Industrial automation control system: In the control cabinet and distribution box of automated production line, it is widely used to terminate and connect all kinds of control signals, power signals and other lines, such as the connection lines between PLC and sensors and actuators, to ensure the stable operation of the production line.
Power electronic equipment: in the frequency converter, inverter, soft starter and other equipment, used to connect the internal circuit board with the external power supply, motor and other lines, play the role of signal transmission and electrical isolation, to prevent high-frequency signals inside the equipment, high voltage and other external equipment and personnel.
Intelligent building electrical system: in the lighting control system, security monitoring system, elevator control system, etc. of intelligent buildings, it can be used to connect the signal lines between each device to ensure the normal operation and safety of the system.
Rail transportation field: in the signal system, power supply system, vehicle control system, etc. of subway, light rail and other rail transportation, it can be used to connect the lines between various electrical equipments and control modules, to ensure the safe operation of trains and the accuracy of signal transmission.
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
The following analyzers are available for selection:
• Uras26 infrared photometer for the measurement of infrared-active gas components, e.g. CO, NO, SO2
• Limas23 ultraviolet photometer for the measurement of NO, NO2 and SO2
• Magnos206 oxygen analyzer for the measurement of O2 in process gas or in N2
• Magnos28 oxygen analyzer for the measurement of O2 in process gas or in N2
• Magnos27 oxygen analyzer for the measurement of O2 in flue gas or in N2
• ZO23 trace oxygen analyzer for the measurement of O2 in pure gases (N2, CO2, Ar)
• Caldos27 thermal conductivity analyzer for the measurement of binary gas mixtures with different thermal conductivity, e.g. Ar in O2, H2 in Ar, CH4 in N2
• Fidas24 flame-ionization detector for the measurement of hydrocarbons
• Electrochemical oxygen sensor for the measurement of O2
