INFORMATION

Description

The LM4 is an digital and/or analogue signals centralizer (depending type).
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.

Other features of LM4A-2IO-M:

  • Telemanagement of the 2 digital outputs
  • Supervision of the 2 digital inputs
  • Monitoring of the 4 analogue inputs

Applications

Reading of any pulse-emitting meter (up to 4 devices). These parameters are useful for generating bills or for specifying a price/unit cost

  • The outputs available on the device can control contacts (gas, water, steam, etc.), and sound and/or light devices to provide protection or alarms by using an internal relay.
  • Detection of logical states for electrical switching or alarms that can control relays through software or modbus communications.
