INTRODUCTION

Logo is something that is perfectly suited for creating and implementing simple automation tasks in the industrial world along with all sorts of building management system. Logo system is something through which one can solve any simple control task. By using the expansion modules logo, one can able to control the most complicated control task in a simple manner without facing any problem. A verity of components usually makes it possible to individually enlarge logo to 24 digital input, 16 digital outputs, 8 analog inputs and 2 analog outputs. It is using for easy expansion by means of a text display or expansion units for a trustworthy solution. Siemens logo digital output module is such a blessing that make automation work easily handled.

Siemens 6RS7222-1BH32-0XBO is the model number of Siemens logo digital output module. In this model, the supply voltage runs through permissible range lower limit 20.4 voltage and permissible range upper voltage 28.4 range. The input current runs through from backplane bus 5 V DC is maximum 140mA. It is 2.5 W power loss type. In it, the number of digital outputs is 16, and in groups, it is 1. It has not short circuit protection provided externally. The limitation of inductive shutdown voltage to typ.(L+)-48V. The switching capacity of the outputs with resistive load is maximum 0.5A, and on the lamp load, it is maximum 5 W.

The output voltage is in rated value is 24V, for signal 0, it is maximum 0.1V, with 10 KOhm load, and for signal 1, it is minimum 20 V DC. In the terms of relay outputs, the switching capacity of contacts with inductive load is maximum 0.5A, on lamp load is maximum 5W, with resistive load, it is maximum o.5A. The shielded cable length is maximum 500m, and an unshielded cable length is maximum 150m.

In terms of interrupts, diagnostics or status information, it has alarms, diagnostic, and monitoring the supply voltage functions.  For status of the inputs, for maintenance, and for status indicator digital output, it has diagnostic indicator LED. Between the channel, in groups of potential separation digital output is one, and between the channel and backplane bus it is 500 V AC. It has approvals and certificates of CE mark, CSA approval, UL approval, cULus approval, FM approval and so on.

In terms of ambient condition, the free fall height is maximum 0.3m, five times in dispatch package. The permissible temperature range is -20 degree Celsius to +60-degree horizontal mounting, -20 degree to 50-degree vertical mounting and 95% humidity.

It can be modularly increased up to 50 I/Os, all three phases can be combined together. Users can toggle between two languages. It has controllable backlight of both displays can also be used in continuous operation. It has password protection to stop mode on TV.

It has program memory which can expand things to 400 functions blocks, has stop watch and analog filter, macro and library functions and data logging functions.
