About the 57C414

Reliance Electric designed the 57C414 to be a Modbus Interface Module. This device was very possibly also put out by Baldor Reliance or Asea Brown Boveri depending on what year it was in mass-production.

The 57C414 was originally designed to be a component in an AutoMax control system. It functioned as a Modbus Assembly Gateway Module. Its primary directive was to promote communication between AutoMax and Modbus devices and connect them. It used a specific set of Modbus directive to do this. The 57C382 has the ability can use one to four AutoMAx Processors that care on the same rack system and then used them like a Modicon 584 style device. It could then be perceived by the Modbus link. This device had the capability to support both RTU and Modbus ASCII modes.    

On the faceplate of the 57C414, there are two thumbwheel dials that are labeled DROP NUMBER. One of them is also labeled 1st and the other is labeled 2nd. These switches are used to label a device's number for equipment or the network. There is an RS-232 female connection labeled GATEWAY. This port provides a way to communicate with non-AutoMax equipment.  There is a pair of LED indicators that are labeled FAULT CODE. One of them is a 7-segment LED. The other is a green OK indicator. The FAULT CODE indicator’s purpose is to alter you with error codes when it detects system defects. The 57C382 is attached directly to the backplane of an AutoMax storage rack. It can be slid into two female card slots.
