substitute i/o cards, people choose this Ethernet I/O module, connect PLC for building automation(HVAC control in a clean room)
Introduction of customer and use scenarios Clean rooms are widely used in pharmaceutical factories, microbiological products factories, research institute laboratories, microelectronics, semiconductors, Photovoltaic and other industries. The humidity, temperature, and airflow pressure in the clean room are very important, and need real-time monitoring, precise adjustment and control, and automatic management is essential. Therefore, the automation control of the HVAC control system is the key issue.
In this project, customer is the clean room of a pharmaceutical factory in Brazil, which uses PLC to control the HVAC system. The connection between the PLC and the field instruments is the i/o card for Wago PLCmodel 750-8212
Its for a microbiology laboratory test, customer test contamination of vaccine. This company make vaccines, serums against sneaks and spiders poison, they do R&D about drugs too.
Challenge The customer is facing to these challenges: * Too expensive PLC needs a particular I/O card of proprietary , so the cost per I/O port is very high. wago plc cost about 20 USD per DO or DI and 60 USD per AI point * user experience is bad hard to PLC programming, too slow communication, there are conflicts to polling
[ SOLUTION ] Solution provider is LGRN company in Brazil. LGRN company choose Ethernet I/O module M160T to substitute I/O card. The cost of Ethernet I/O module is less than USD200 but support 8 channels DI , 8 channels Analog input and 8-channels DO, therefore the average cost per I/O can reduce more than 50%.
Solution topology diagram:
[RESULT] With the help of solution provider who replace PLC card with M160T Ethernet I/O module, the customer pay less money on automation of HVAC but get better clean room use experience.
Benefits: reduce cost per I/O by more than 50% simplify wiring Easy expansion Few conflict, communication connection more reliable
Customer Testimonials I tried many solutions, plc card, others I/O remote The m160t is the best The reasons of choosing M160T:
Cost per I/O better than plc card
the plc card refer to i/o card wago plc cost about 20 usd per DO or DI and 60 USD per AI point All plc card I know is always particular，means special for wago brand only, Proprietary
Ethernet connection is a big diferenttial
because M160T support Ethernet connection , it is better over others connection that uses rs485. And It is more confiability. the m160t works uninterrupted all time, works all function. Fass communication.
Possibility expansion points on RS485 port
because M160T has RS485 port, there is possbility of expansion. expanse to support more sensors/instruments/data points
There other advantage the only modbus map, only ID and IP
With m160t we can do only one map registers with one ID and one IP address PLC see only “ONE”device only one register map for all instruments/ sensors /devices
Easy PLC programming
Direct access to 8AI, 8DI, 8DO, substitute for PLC card is really good !
