There are a great variety of input output (I/O) modules that allow the exchange of information between the PLC and the process.
Input modules send information of the process state to the PLC and output modules send information from PLC to the actuators that modify the process state.
Description of input output modules
The input output modules also are classified according to type of signal used, so we have digital modules and analog modules. The digital modules, also called discrete modules, use signals that have only two possible values, for example presence or absence of 120VAC. The most common signals, also called control voltage, are 120 VAC, 220 VAC and 24 VDC, but there are others less frequent.
| Input Output | Input | Output |
| Digital | 120 VAC | 120 VAC |
| 220 VAC | 220 VAC | |
| 24 VDC fuente | 24 VDC fuente | |
| 24 VDC sumidero | 24 VDC sumidero | |
| Relé | ||
| Analog | 4-20 mA | 4-20 mA |
| 0-10 VDC | 0-10 VDC | |
| Termopares | ||
| RTD |
There are others types of input output modules with special applications as are high speed counter, weight, networks and control motion among others.
Input connections
The input connections follow the rules of any basic electric circuit; typically there are three elements: power supply, input devices (for example a sensor or a button) and the third element is the input in the input module. The power supply provides power to the input when the input device is closed. The next figure shows this.
Input Connection
The power supply, frequently, is going to be any of those shown in the table above. The input module is chosen according to the control voltage. The modules are designed such way that the input impedance limits the input current to a few milliamps. The flow of the input current can be in both directions, entering or leaving the module depending if the connection is for a circuit AC, DC sink or source respectively. The inputs in the module are grouped and each group has a common point. The voltage of each group can be different. If an input is not in a group, it is called isolated input. In the next figure is shown the more common connections.
AC Input Module
DC-sink Input Module
DC-source Input Module
It is important to note that when a sink input module is used, the input device must be source type and when a source input module is used, the input device must be sink type.
Output connections
The output connections are similar to the input connections, but now the switch element is the output and the output device (i.e. pilots, coil) is the load, as the figure shows.
Output connection
The output module must be chosen according control voltage and the load, the more common modules are designed with triac for AC, transistor for DC and relay that can be used with AC and DC. The outputs also are grouped and those are not grouped are called isolated outputs.
Se debe escoger el módulo de salida según el voltaje de alimentación y la carga. Los módulos de salidas de uso son más frecuentes están diseñados con triac para voltajes AC, con transistor para voltajes DC y con relés que pueden manejar tanto voltajes AC como DC. Las salidas también se agrupan y las salidas que no estás agrupada se les denominan salidas aisladas.

I have realized that over the course of developing a relationship with real estate homeowners, you’ll be able to get them to understand that, in most real estate deal, a percentage is paid. In the end, FSBO sellers tend not to “save” the commission payment. Rather, they fight to earn the commission simply by doing the agent’s job. In doing this, they devote their money plus time to accomplish, as best they’re able to, the jobs of an adviser. Those tasks include displaying the home by way of marketing, delivering the home to willing buyers, creating a sense of buyer desperation in order to trigger an offer, organizing home inspections, controlling qualification investigations with the financial institution, supervising maintenance tasks, and assisting the closing.

Pleural mesothelioma, and that is the most common form and impacts the area within the lungs, might result in shortness of breath, chest pains, and a persistent coughing, which may lead to coughing up blood vessels.

However, being photographer, you should first commit so much time period deciding the model of photographic camera to buy and also moving store to store just so you could possibly buy the lowest priced camera of the brand you have decided to settle on. But it doesn’t end now there. You also have to take into consideration whether you should buy a digital digital camera extended warranty. Thanks a lot for the good tips I accumulated from your site.

I’ve learned newer and more effective things through the blog post. One more thing to I have seen is that generally, FSBO sellers will reject anyone. Remember, they will prefer to not ever use your services. But if you maintain a stable, professional relationship, offering assistance and remaining in contact for four to five weeks, you will usually manage to win a conversation. From there, a house listing follows. Thank you
This article is a breath of fresh air! The author’s distinctive perspective and insightful analysis have made this a truly fascinating read. I’m thankful for the effort he has put into crafting such an educational and provocative piece.

It’s my opinion that a home foreclosure can have a major effect on the applicant’s life. Real estate foreclosures can have a Seven to a decade negative affect on a applicant’s credit report. A new borrower having applied for a home loan or virtually any loans for that matter, knows that a worse credit rating is actually, the more complicated it is to obtain a decent mortgage loan. In addition, it could affect a borrower’s capability to find a respectable place to let or rent, if that gets the alternative real estate solution. Great blog post.
