The 57C554 is an AutoMax Remote I/O Shark Interface Module. This module was initially made by Reliance Electric and had at one point been possibly manufactured by ABB and Baldor Reliance. This card is no longer in production and can be a little hard to find. AX Control does make every effort to ensure that it is kept in stock as either a refurbished or new surplus part. This module can also be found under the part number 0-57554.
The 57C554 is used to connect a Shark remote rack to the AutoMax Remote I/O Network. It can interface to a Shark remote rack’s backplane using a built-in microprocessor that helps with basic buffer circuitry and timing. The power for the logic circuitry on this card is provided by the rack it is attached to. The power supply is rated +5 VDC. There is a different power supply that is rated +24 VDC and regulated at +12 VDC that is mounted onto the rack for the module’s I/O network.
This small card has a few things on its faceplate. It has two green LED indicators that are labeled CPU OK and COM OK. There is a drop number dial in the center of the faceplate. This card also has a female RS-232 9-Pin d-shell serial connection port that is labeled network. There are two small clips on the faceplate that are used to help mount and remove the card from the rack storage device.
Only a trained professional should attempt to mount this card into a Shark Remote Card Rack Assembly.
