Allen-Bradley 1785-05G B Interface Coprocessor Module is a PLC-5 MAP/OSI coprocessor that installs in a PLC-5 rack to provide 802.4 MAP/OSI communications between the controller and MAP/OSI devices. It is powered from a 5 V DC supply, drawing up to 2.7 A, enabling the coprocessor and its interface circuitry to operate reliably within the backplane environment. This Series B module is designed for industrial automation applications that require OSI MAP/OSI connectivity to extend PLC-5 capabilities to MAP/OSI networks by serving as the interface coprocessor for PLC-5 systems.
