Introduction to S7-200 Accessory Module EM221 8DI, 24 VDC
It is a thing which works as a micro-programmable logic controller used to control a huge kind of devices to run the automation world smoothly. It basically looks up and monitors the input system and changes outputs according to the need of a customer. This S7-200 Accessory Module EM221 8DI, 24 VDC besides controlling any program, it also operates Boolean logic, counting, timing, complex math operations and communication system to a great extent.
The S7-200 Accessory Module provides a user-friendly and contented atmosphere to procreate, control and monitor any logic to create a complete program. It is in a simple word, a small CPU for the normal automation task as it is the perfect small device for having a cost-effective programming solution. To expand the temperature range it can also be used. This is very beneficial for small but complex work, more complex machines and small systems solutions with component compact packages. In EM 221 8DI, PLC module is 24VDC 16 DI compatible Siemens s7-200 accessory.
This S7-200 accessory module EM221 8DI, 24VDC is fully compatible with s7-200 and s7-300 series programmable logic controller, STEP 7 software like MICRO/WIN where programming can be used directly by enhancing encryption algorithm for S7-200. EM series PLCs are high qualified, user-friendly and fully compatible with CPU, and the other device.
In the automation world, things become so easy and easy handled by using these devices, it is not only making everything easy but also give a cost-effective solution for the accessories. S7 200 accessory module is a product family of the SIMATIC 200 series.
In it, the product type designation is BU type A0, HW functional status states from FS06. It supplies voltage in 24 V rated voltage (DC). It is 24 V DC/A miniature circuit breaker with type B or C tripping characteristics for an external protection power supply line.
It has no mains filter. For P1 and P2 bus, max current carrying capacity is 10 A, and for process terminals maximum current carrying capacity is 2 A. In the term of hardware configuration, it has an automatic coding system, but it has no formation of potential groups. In it, potential the group continued from the left.
In the S7-200 accessory module, Its isolation tested with 707 V DC. It has many Ambient temperatures during operation. In the horizontal installation, min is -30 degrees Celsius and a maximum of 60 degrees Celsius. On the other hand, in the vertical installation, min is 30 degrees Celsius and the maximum is 50 degrees Celsius. Installation altitude above sea level maximum is 2000 m; on request installation altitude is greater than 2000 m. For process terminals, color coding labels are CC00 to CC09, for AUX and add on terminals it does not exist.
