Abstract

The utility model provides a redundancy output terminal board which is short in switching time and has a small influence on a sampling feedback loop. The redundancy output terminal board includes 13 relays, a first redundancy analog output sub-module, and a second redundancy analog output sub-module. The first redundancy analog output sub-module is connected with a first socket, and the second redundancy analog output sub-module is connected with a second socket. Each of the first redundancy analog output sub-module and the second redundancy analog output sub-module is provided with 14 AOs. The 13 relays are connected with 13 AOs of the first redundancy analog output sub-module and 13 AOs of the second redundancy analog output sub-module respectively. The fourteenth AO of the first redundancy analog output sub-module and the fourteenth AO of the second redundancy analog output sub-module are connected with comparators. The redundancy output terminal board is provided with 2 redundancy output sub-modules, and the switching time is at the ms level, thus having little influence on a device or a user sampling feedback loop.

Description

A kind of redundant output daughter board

Technical field

The utility model relates to a kind of redundant output daughter board, especially a kind of redundant output daughter board that is used for ABB Harmony control system IMASO control module.

Background technology

Be not specifically designed at present the terminal board of the redundancy output of IMASO control module in the ABB Harmony control system, existing redundant output daughter board, relay is long switching time, causes the data sudden change when switching easily.

The utility model content

The utility model provides a kind of switching time short, to the little a kind of redundant output daughter board of sampling feedback loop influence.

Realize a kind of redundant output daughter board of the utility model purpose; Comprise 13 relays, the first redundant analog quantity output submodule part and the second redundant analog quantity output submodule part; The said first redundant analog quantity output submodule part is connected with first socket; The said second redundant analog quantity output submodule part is connected with second socket respectively; The said first redundant analog quantity output submodule part and the second redundant analog quantity output submodule part all are provided with 14 AO; Said 13 relays link to each other with 13 AO of the said first redundant analog quantity output submodule part and the second redundant analog quantity output submodule part respectively, and the 14th AO of the said first redundant analog quantity output submodule part and the second redundant analog quantity output submodule part is connected with comparator respectively.

Be respectively equipped with fuse between the said first redundant output submodule part and first socket and between the second redundant output submodule part and second socket.

The beneficial effect of a kind of redundant output daughter board of the utility model is following:

1, be provided with 2 redundant output submodule parts, a sub-module fault and quitting work or output abnormality, output switches to another submodule part immediately, and be the ms rank switching time, to equipment or the almost not influence of user's sampling feedback loop.

2, adopt signal relay at a high speed, guarantee switching device life-span and reliability.

3, adopt the comparator of integrated chip to make up AO fault evaluation loop.

Embodiment

Embodiment 1

As shown in Figure 1; A kind of redundant output daughter board of the utility model; Comprise 13 relays, 7, first redundant analog quantity output submodule the part 1 and second redundant analog quantity output submodule part 2; The said first redundant analog quantity output submodule part 1 is connected with first socket 3; The said second redundant analog quantity output submodule part 2 is connected with second socket 4 respectively; Said first redundant analog quantity output submodule the part 1 and second redundant analog quantity output submodule part 2 all is provided with 14 AO, and said 13 relays 7 link to each other with 13 AO of the said first redundant analog quantity output submodule part 1 and the second redundant analog quantity output submodule part 2 respectively, and the 14th AO of said first redundant analog quantity output submodule the part 1 and second redundant analog quantity output submodule part 2 is connected with comparator 6 respectively.

Be respectively equipped with fuse 5 between the said first redundant output submodule part 1 and first socket 3 and between the second redundant output submodule part 2 and second socket 4.

Embodiment 2

The redundant output daughter board of NTAO02-AR links with 2 redundant analog quantity output submodule part IMASO11 through 2 NKTU01 cables (through 2 cable sockets); 1 MASTER socket of linking NTAO02-AR wherein, other 1 SLAVE socket of linking NTAO02-AR.Each IMASO11 submodule part has 14 AO output signals.The 14 road AO of MASTER IMASO11 module wherein, Configuration Design makes its output fixed value 20mA; The 14 road AO of SLAVE IMASO11 module, Configuration Design makes it export fixed value 20mA.The 14 road AO of MASTER through comparator, judges whether this road output is normal in NTAO02-AR; Otherwise think that the IMASO11 module of MASTER has problem, 13 relays will be outputted to the SLAVE module to 13 road AO; And if the 14 road AO output abnormality of the IMASO11 module of SLAVE, then SLAVE will not export, relay will be failure to actuate, the MSATER module is still received in 13 road AO output.If 1 IMASO11 module damages and not output like this, other 1 IMASO11 module will drive AO.

Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
