Embodiment Construction

[0021] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0022] combine Figure 1-6 , the embodiment of the present invention provides a schematic structural diagram of a pluggable IO module. The IO module includes a base 1, a daughter card 2, a fixing part 3, and a pluggable fuse 4. The daughter card 2 is detachably installed on the base 1, and at least one fuse hole 10 is opened on the base 1, and the pluggable fuse 4 is inserted into the hole of the fuse 10. The base is provided with a card slot, and at least one daughter card 2 is detachably inserted into the card slot. Most of the sub-cards and bases of the IO modules currently on the market are connected by means of screw fastening, and special tools for disassembly and assembly are required during replacement and maintenance; the fuse is also arranged in the internal circuit of the module. The card 2 is detachably connected...

Abstract

The invention discloses a pluggable IO (input/output) module and a DCS (distributed control system), the pluggable IO module comprises a base, a daughter card, a fixing part and a pluggable fuse, the fixing part is used for detachably mounting the daughter card on the base, the base is provided with at least one fuse hole, and the pluggable fuse is inserted into the fuse hole. According to the pluggable IO module, the base is detachably connected with the daughter card, so that the problems that the module is not easy to disassemble during maintenance and is troublesome to disassemble and assemble are solved; the fuse hole is formed in the base, so that the pluggable fuse is exposed outside the module shell, whether the fuse is fused or not can be judged timely and accurately, replacement is very easy to operate, and the pluggable IO module has the advantages of high reliability, high maintainability, high stability and the like.

Description

technical field [0001] The invention belongs to the field of input and output equipment of an automatic control system, and in particular relates to a pluggable IO module and a DCS system. Background technique [0002] With the wide application of Distributed Control System (DCS) in smart energy, electric power, chemical industry, water treatment, building and other industries, the market scale is getting larger and the competition is becoming more and more fierce. Users have put forward higher requirements on the performance, cost, ease of use and other aspects of the DCS system. The performance, cost, ease of use and other indicators of the DCS system are mainly determined by the input and output modules (IO modules) in the DCS system. The module design of a compact, powerful, reliable, easy-to-use and easy-to-maintain DCS system becomes particularly important. [0003] In the existing automation control field, most of the signal input and output modules used by mainstre...
