Electrical energy meters for partial consumption Centralizing unit with 4 inputs Impulse CENTRALIZING UNIT Centralizing unit with 4 optocoupled inputs and 4 relay-type outputs, with RS-485 communications Description 4-input impulse centralising equipment. Inputs are optoisolated to read impulses and it has a 32-bit memory to store the values metered. }} has an RS-485 communications port It that can be used with an RS-232 or Ethernet converter to read and write the unit's records remotely, using the PowerStudio management software. The RS-485 bus can be used to connect up to 32 units that use this type of communications }} unit's outputs can be programmed to The generate impulses or for remote control actions with the PowerStudio software Features Power supply circuit Digital inputs 4 optoinsulated inputs (voltage-free) Maximum activation current Nominal voltage Electrical endurance Nominal current With resistive load With inductive load (ac) With inductive load (dc) Ambient conditions }} Reading any Impulse-emitting device (up to 4 units). These parameters are useful to generate receipts or define a price/unit cost }} Alarm central: the unit's outputs can act on contacts, sound and/or luminous devices to carry out a protection or warning operation with an internal relay.
