LM4A-2IO-M Analogue and digital signals centralizer

Main features The LM4A-2IO-M is an analogue and digital signals centralizer. In only 4 DIN modules, the unit has 2 relay outpus and centralizes 4 analogue inputs from 0 ... 20 mA, 2 voltage-free digital input. The unit includes an RS-485 communications bus with a Modbus/RTU protocol, which allows real time control by communications. The unit is compatible with PowerStudio and PowerStudio SCADA control software. Control Telemanagement of the 2 digital outputs: yyOpen relay function yyClosed relay function yyImpulse function Humidity probe

Management The LM4A-2IO-M enables to easily monitor and remotely control any industrial process signal thanks to the PowerStudio / PowerStudio SCADA energy management software. Ethernet TCP2RS+ is a gateway aimed at conversion of the physical medium Ethernet to RS-232 or RS-485, or vice versa. The unit has a Web Server for configuring its parameters. Supervision Water meter Supervision of the 2 digital inputs: yyVoltage-free inputs yyDetection of the logic state of the inputs yyCentralization of digital impulses received by external meters (≤ 10 Hz) Display Monitoring of the 4 analogue inputs:...
