Actuator sensor Interface


Actuator sensor interface is a field level interface which connects input field elements like push buttons, sensors and feed back elements and output field elements like contactors, relays and solenoids. The input output modules are available in panel mountable or field mountable models. IP 65 protection of the field module enables to locate any where in the field without a need of panel. Safety integrated Modules are also available . All input , output modules can be connected with a single specially manufactured ASI cable which reduced cabling between field elements and CPU. The system can be connected to S7-200 and S7 -300 systems.

Distributed Systems

ET 200 S Systems:

6  7  8

A compact PLC used in Distributed Profibus / Profinet systems where small group of I/Os are  located in groups in a plant distributed over a large area. The modules as small as 4 digital  inputs and 4 digital outputs or 2 analog inputs are available as individual modules at an economical pricing and  the ET 200S modules can be supported with an interface module and connects by Profibus cable or Profinet cable. This enables localized PLC systems near to field equipments enables easy monitoring and a boon to maintenance engineer. It reduces cabling between each input/output to field equipments and a simple Profibus/Profinet cable connects the system to Main PLC.
