07EA90-SI GJR5251200R0101 ABB Analog Input Module

Description

ABB 07EA90-SI GJR5251200R0101 Control card system integration controllable module

The ABB 07AC91 GJR5252300R0101 module is an analog I/O module used in distributed automation systems. It has 8 analog inputs and 8 analog outputs, with selectable modes and voltage/current ranges. The module is part of the AC31 series and is designed for use with a 24V DC power supply. The module can be mounted on a DIN rail using TH35-15 or TH35-7.5 mounting rails. The module has various certifications and complies with IP20 protection standards. The module supports multiple communication interfaces, including CS31 and RS-485. The module has a product depth of 85mm, a net height of 140mm, a net length of 85mm, and a net width of 120mm. The module weighs 0.81kg and has a voltage rating of 24V DC.

(1) I/O points selection

The average price of PLC I/O points is still relatively high, so the number of PLC I/O points should be reasonably selected, and strive to use the least I/O points under the premise of meeting the control requirements, but must leave a certain margin.

Usually I/O points are determined according to the actual needs of the input and output signals of the controlled object, plus a margin of 10% to 15%.

(2) Storage capacity selection

The storage capacity required by the user program is not only related to the function of the PLC system, but also related to the method of function realization and the level of program writing. An experienced programmer and a beginner can vary as much as 25 percent in the amount of programs they use to perform the same complex function, so beginners should leave a margin for storage capacity estimates. The number of PLC I/O points reflects the functional requirements of the PLC system to a large extent, so it can be determined on the basis of I/O points, and then add 20% to 30% margin after estimating storage capacity according to the following formula. Storage capacity (bytes) = Number of switching I/O points x 10 + Number of analog I/O channels x 100 In addition, when selecting storage capacity, pay attention to the selection of memory type.

PLCI/O module selection steps and principles

The price of the general I/O module accounts for more than half of the PLC price. PLC I/O module has switching I/O module, analog I/O module and various special function modules. Different I/O modules, its circuit and function are also different, directly affect the application range and price of PLC, should be selected according to actual needs.
