U1660

U1660 LON-Add-On Component Meter Reading Module 3-349-214-03 2/12.05 8 active S0 pulse inputs required pulse duration > 100 ms LED state display FTT-10A transceiver (78 kBit/s) Standard network variables for energy, instantaneous power and state LED status display QUALITY MANAGEMENT SYSTEM DQS certifizied per DIN EN ISO 9001 Reg. No.1262 Applications The LON add-on component is used for scanning measuring points within the energy control system in a decentralized fashion. The U1660 meter reading module processes data from up to 8 energy meters with pulse output (S0), or floating contact. The active inputs do not require any additional power supply which minimizes wiring expenses. The add-on component expands the functions offered by the U1601 summator, the U1602 micro-summator and the U1603 mini-summator to include external inputs via the LON interface. Display Elements Power LED Active LED On: On: Operating voltage on S0 inputs are supplied with voltage. If the adapter is in unconfigured or offline state, the LED is off and the SO inputs are not supplied with voltage. Signals the state of the LON node („Service LED“), is activated for 2 seconds upon receipt of a wink command. On: Module has no application Blinking: Module is not configured On: Current flow via pulse contact of the meter Error LED Function U1660 is a meter reading module with eight active inputs. It determines energy and instantaneous power on the basis of SO pulses. The valence of a pulse (...
