Elinker Electric company staff analysis of the rapid wiring Terminal Board common mistakes: quick connection terminal Board, the product will be within the control cabinet wiring electrical accessories designed as modular series, including a variety of analog and digital signal input/output, power distribution, unified standard mounting dimensions, components, transparent design, indicates at a glance. For automation system integrators in the design, manufacture, control cabinet and brought great convenience when the control box, control cabinet assembling and wiring, and even directly in the project sites, completely solve the long-term problem that plagued the people also bring great convenience to maintenance personnel. Bring great convenience to system integration, operation and maintenance.
1, both Terminal and in the relays, there are plenty of line contact, wiring process is complex and long duration, high failure rate.
2, different forms of control instruments of signals of different lead wiring methods are distinct, needs power transmission instrument introduced the power cables from the power distribution unit, loop-powered transmitters directly into the input side, either voltage or current signals, from the drawings it is difficult to figure out the line to
3, and currently market Shang of enjoy DCS and PLC module using of points line manager and following electric module features General comparison simple, needs outside enjoy large of leads, as Figure 3, and Figure 4 by shows, and dry contact output of module for solution contact type type (often open often closed) of uncertainty, General put two species touch points while leads, occupy has valuable of machine cabinet space. Analog signal splitters are used to introduce the template, its role is only line.
4, due to large amount of loop power supply automation system such as DCS/PLC, transmitting meter did not have matching power distribution device, stop the clock remove table problem difficult to solve, stitches approach General daily maintenance outage, not only inconvenient but also access to other live contact or wrong at restore time.
5, detects the current signal during repair stitches must be used with ammeters, interrupted the normal procedures for measuring, if circuit in automatic State, could easily cause malfunction occurred accidents in production.
6, normal screw-type terminals vulnerable to the installer personal habits no pressing cause poor contact.
7, many devices are power insurance, individual failures lead to multi-loop power outages, single-loop protection insurance are commonly used when the Terminal has also increased the number of contacts.
8, large power distribution switches.
9, card and module power require special wiring.
Elinker Electrical company limited as the professional terminal blocks, relay module manufacturer, always adhere to the "scientific and technological innovation, quality service," the concept of enterprise development. Fast Terminal plates are mainly used in large-scale industrial production plant supporting system of large and medium sized DCS system, PLC and remote IO (RTU) installation is based on industry standards, process control system and instrument height adaptation dedicated integrated development interface enables seamless connection with the control system, completely solved the wiring process uncertainty, adapted to the needs of industrial automation technology development.
