INFORMATION

Description

Impulse centralizing unit, with up to 50 devices. The inputs of the centralizing unit are optocoupled to read the said impulses and it also has a memory to store up to 32 bits of data. It has two communications ports:

  • RS-485 Port: It can be used to connect up to 31 CIRCUTOR units that can be monitored with the PowerStudio software. This port acts as a gateway from Ethernet to RS-485
  • Ethernet 10Base / 100Base TX Port that can be used by the PowerStudio energy management software to carry out the read and write operations of the 50 inputs of the LM, and all other units in the RS-485 network.

Applications

  • Reading of any device that emits impulses (up to 50 devices). These parameters are useful for generating bills or for specifying a price/unit cost
  • Integration with other consumption, such as: gas, water, etc. or simply to track the energy consumption of 50 meters
  • As an alarm centre: taking action based on the status of the device outputs, or triggering an alarm following a change in status
