Edwards EST SAN-CPU CPU Card, RS-485 Interface

The SAN serial annunciator is a member of the data line and consumes one panel address. The SAN annunciator is not only an annunciating device but may be configured as a system control center. SAN option modules are connected via ribbon cable to the CPU card to customize the configuration of the annunciator per your requirements. Each SAN option module is 10.25 in x 2.75 in (HW) metal plate with standoffs on the rear with a control PC card. The front of each SAN module is covered with black LEXAN overlay with a legend pocket for those modules requiring switch and LED legends. A legend sheet in a choice of five different colors comes with each module so the legend may be typed adjacent to each switch or LED and inserted into the pocket. Each SAN module mounts to the SAN cabinet with black anodized screws. Each SAN contains a CPU card capable of supporting 96 inputs and 96 outputs (one panel address). The SAN may be configured using an RS-485, 20 mA data line.
