Accura 2750LCG LOP Controller[Accura 2750LC] Gateway
Accura 2750LCG performs two-way data transmission function between Accura 2700M and multiple Accura 2750LC. Accura 2750LCG supports two RS-485 ports to communicate to two Accura 2700Ms for device redundancy.
Accura 2750LCG supports two RS-485 network groups[2 ports for each group] for communication with multiple Accura 2750LCs. It supports communication redundancy by ring connection of Accura 2750LC using 2 ports at single group. Up to 20 Accura 2750LCs can be connected by single ring connection and maximum 40 can be connected by two ring connections.
Accura 2750LCG supplies Accura 2750LC control power 24V DC through communication cable. Due to the limit of power supply ability of Accura 2750LCG, in case that the number of Accura 2750LC exceeds 10 for each RS-485 communication network group, an Accura 2750LC POW module should be equipped to the rear side of Accura 2750LC in order to operate up to 20 Accura 2750LCs per group, additionally.
