A1S-J71QLP21

The Mitsubishi A1S-J71QLP21 is a Network Module that provides efficient and robust communication capabilities. This module handles many link points per network, supporting up to 8192 points. The communication speed is impressive, offering a maximum of 10 Mbps, with a higher speed of 20 Mbps achievable through multiplex transmission. For communication, the A1S-J71QLP21 utilizes a Token ring mode and operates in a synchronous manner with Frame synchronous mode. Its transmission circuit format is a Double loop, ensuring reliable data transfer. The module allows for the establishment of up to 239 networks, and in a PC network configuration, it supports a maximum of 9 groups. Constructing a PC network with this module allows connections for 64 stations, consisting of one control station and 63 normal stations. On the other hand, a remote I/O network setup can accommodate 65 stations, including one remote master station and 64 I/O stations. The coding mode utilized is NRZ1 signal (non-return to zero inverted), and the transmission format follows HDLC performance with frame formatting. With N : N intercommunication, transient transmission is facilitated seamlessly. In terms of power consumption, the module operates at a low 0.65 amperes for 5 volts DC, which contributes to energy efficiency. For external supply voltage, it requires 20.4 to 31.2 volts DC, with a current demand of 0.2 amperes. The A1S-J71QLP21 offers a generous I/O occupancy, with support for up to 48 points. It occupies two slots in the system, providing the necessary flexibility for integration with other modules and devices.
