Accura 2750LCG LOP Controller[Accura 2750LC] Gateway
Accura 2750LCG performs two-way data transmission function between Accura 2700M and Accura 2750LC[I]. Accura 2750LCG supports two RS-485 ports to communicate with two Accura 2700Ms for redundancy.
Accura 2750LCG supports two RS-485 networks(2 ports for each group) for communication with Accura 2750LC[I]. It supports communication redundancy by ring connection of Accura 2750LC[I] using 2 ports within single group. Up to 20 Accura 2750LC[I] can be connected by single ring connection and maximum 40 can be connected by two ring connections. Accura 2750LC[I] control power 24V DC is supplied through communication cable. Due to the limit of power supply ability of Accura 2750LCG, in case that the number of Accura 2750LC[I] exceeds 10 for each RS-485 communication network, one additional Accura 2750LC POW module should be added at the rear of Accura 2750LC[I] to operate up to 20 for each group.
