Description
Technical field
The utility model provides a kind of interface arrangement, especially a kind of for PLC the terminal board of DCS system and safety barrier (or isolator) and peripherals.
Background technology
Automatic control system and weak electricity system extensively adopt at present DCS or PLC or carry out centralized control.In commercial plant control, the application scenarios such as chemical device with fire and explosive hazard generally need to form the Sefe antiexplosion system with safety barrier, have more strongly disturbing occasion then normal operation signal isolator (abbreviation isolator) carry out signal conversion, to improve antijamming capability.At present generally adopt guide rails assembling and terminal connections mode in the safety barrier of usefulness, the assembling mode of isolator.There is following problem in this assembling mode: 1, assembly process is many, and operating process is more loaded down with trivial details, and is higher to workman's technical requirement, long in time limit and the misconnection misconnection occurs easily.When 2, cooperating the DCS of different brands and PLC, need to carry out the differentiation of the mode of connection and process, when job design, need to skillfully grasp system hardware, higher to designer's competency profiling.3, a large amount of distributions and crimping point is prone to the loose contact problem, for system debug and long-time running hide some dangers for.4, every safety barrier, isolator all need distribution, increase power distribution equipment, realize that the power supply redundancy difficulty is larger.5, the terminal intensity of safety barrier, isolator is generally lower, and failure rate is higher.6, to the safety barrier that breaks down, must take out stitches when isolator carries out maintain and replace, prolonged the downtime.In a word, existing assembling mode result of use is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide the high-speed wiring terminal block of a kind of safety barrier, isolator, to improve its result of use.
The utility model is to realize like this, a kind of safety barrier, the high-speed wiring terminal block of isolator, it has printed circuit board (PCB), the top of printed circuit board (PCB) is equipped with the DB25 socket, power supply terminal and power pin wire jumper, the other power light that has light emitting diode to form of power supply terminal, interface socket is equipped with at the middle part of printed circuit board (PCB), the bottom of printed circuit board (PCB) is equipped with signal input output end, be fixed with housing above the printed circuit board (PCB), each components and parts that is installed on the printed circuit board (PCB) are electrically connected and are exposed by the hole on the housing through P.e.c., and there is buckle the up and down both sides of interface socket.
Adopt the terminal board of said structure, rational in infrastructure, result of use is good, and it has the following advantages: needn't take out stitches when 1, changing safety barrier, isolator, directly plug has improved overhaul efficiency, has reduced the downtime again.2, safety barrier, isolator are connected no longer separately distribution with the signal of DCS or PLC, and adopt private cable directly to peg graft.Like this, improve wiring efficiency, shortened the duration, simplified the distribution job design, be fit to the more large scale system signal transmission of switch board, simplified the connection of dish top-stitching.3, efficiently solve the signal assignment problem of hardware system redundancy.4, safety barrier, isolator needn't connect power lead more one by one, and adopt public power supply, have simplified power supply wiring, and have realized power supply redundancy, power supply indication, also can realize the power down warning.5, connection terminal intensity is large, has reduced the failure rate of connection terminal, has stopped to scrap because the terminal fault causes device.6, change pad into by original a large amount of crimping contact, reduced the incidence of loose contact, improved the reliability of system.7, components and parts integrated after, copper wire is applied in the short distance printing that original long distribution changed on the printed circuit board (PCB), former exposed single core loose wire changes the private cable of shielding into, has reduced the impact of external electromagnetic interference on signal.8, can be supporting with other switch board fast-wiring products, greatly reduce the complicacy of switch board distribution, reduce recruitment, making the assembling of switch board transfer to building-site by factory becomes possibility.

Fig. 3 is the cross-sectional view after the utility model is installed safety barrier or isolator.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
As shown in drawings, a kind of safety barrier of the utility model, the high-speed wiring terminal block of isolator, it is characterized in that, it has printed circuit board (PCB) 2, the top of printed circuit board (PCB) is equipped with DB25 socket 3, power supply terminal 4 and power pin wire jumper 5, the other power light 6 that has light emitting diode to form of power supply terminal, interface socket 7 is equipped with at the middle part of printed circuit board (PCB), the bottom of printed circuit board (PCB) is equipped with signal input output end 9, be fixed with housing 1 above the printed circuit board (PCB), each components and parts that is installed on the printed circuit board (PCB) are electrically connected and are exposed by the hole on the housing through P.e.c., and there is buckle 8 the up and down both sides of interface socket.
The DB25 socket adopts redundant configuration, is used for connecting DCS fastener or the PLC module of concentrating lead-in wire, and powers for fastener or module, and its concrete order of connection is configured according to the interface characteristic of DCS or PLC.
Electric power loop is by dual power supply redundancy In-put design, configurable overcurrent, overvoltage, surge protection circuit and power supply power-fail alarm output circuit.Power light 6 carries out the power supply indication, and the current supply circuit of DCS fastener or PLC module has also been taked corresponding safeguard measure.
Safety barrier or isolator 10 adopt and are connected with printed circuit board (PCB) with its supporting interface socket 7, and use buckle 8 to be fixed to prevent loose or dislocation.Interface socket is private jack, and buckle also is special fastening.
Signal input output end 9 can adopt the high-intensity U.S. rule screw-type double-layer wiring terminal block of four joints, and terminal block can be with the line plug to be convenient for changing whole terminal block.
