Remote io module manufacturers analyze that some complex device sites constitute a large number of control elements. The use of remote io module control system is to solve the problem that field devices need a unified bus interface for bus connection, and also to solve the problem of field explosion prevention. Then, let's learn about the function and overall technical advantages of remote io module together with remote io module manufacturers!

　　Analysis of remote io module manufacturersSome complex devices form a large number of control elements on site. The remote io module control system is adopted to solve the problem that field devices need a unified bus interface for bus connection, and also to solve the problem of explosion-proof on site. Then, let's learn about the function and overall technical advantages of the remote io module!

The remote IO module is a control system used to store the remote IO module system. It sends signals to the system (such as switches) and communicates between cabinets through optical cables to achieve data exchange and ensure signal security. Some systems have independent CPUs, while some systems do not have CPUs as remote expansion racks for inter-rack control systems. The use of remote I/O should be common in places away from the cabinet, such as control rooms, docks, etc.

　　Remote io module manufacturersthe main function of remote io: remote io module technology provides a new choice for field instrument and equipment communication. in the case of long transmission distance, this technology realizes "advanced function and simple installation". one of the main purposes of using remote io module is to solve the problem that field equipment needs unified bus interface to connect bus, this is because configuring a bus interface on each field device is currently neither economical nor practical. On the other hand, in order to solve the problem of on-site explosion-proof, intrinsically safe explosion-proof and live plugging can be carried out, which can save a large number of cables from dangerous areas to safe areas.

Traditionally, laying the line between the ready-made line and the box requires laying the line again and again, which greatly increases the cable cost and construction time, and the distance also needs to face problems such as voltage attenuation. In addition, through the remote IO module, this problem can be effectively solved.

If the storage module is 200 meters away from the site and remote IO is not used, please separate each signal line by 200 meters, and then install the remote IO module on the site to reduce costs and construction complexity, that is, some remote IO The module is installed far away from the central control room, and then connected to the central control room through optical fiber to save cable purchase and construction. In some cases, the logical "remote" needs to connect the "remote IO template", because the allowed number of "local IO" cannot meet the actual needs, which depends on the situation. In addition, common cabinets are placed on the equipment site. However, control signals such as emergency stop and bypass are implemented in the control room, so it is necessary to use the remote IO module to send these signals to the control system in the machine room.

The overall technical advantage of using the remote io module: the configurable remote io module reduces or eliminates the need for grouping, and the field signal can be directly loaded on the remote io module terminal, so there is no need for weaving. This method has many advantages, including reduced material costs, such as cabinets, pipes, internal link cables, cable trays and other support, as well as reduced equipment weight (which is very important for floating oil production equipment), project labor, commissioning costs, and filing costs.
