Industrial 57C424 MaxPakIII High Speed Link Unit

The 57C424 MaxPak III High Speed Link Module from Reliance Electric is an interface card that plugs into the AutoMax DCS rack to act as the High Speed Link bridge for the MaxPak III DC drive, enabling fast, prioritized data exchange between the drive and the host system. The HSL module uses a dedicated RS-232 serial link configured for 41.6 kbaud with 8 data bits, odd parity, and 1 stop bit, employing a null-modem cable (not to exceed 50 feet) to transmit one high-priority integer register per message to support the drive’s inner regulation loop. Dimensions are Height 11.71 in, Width 1.25 in, Depth 7.375 in; power requirements are 5 V at 2,400 mA, +12 V at 53 mA, and -12 V at 8 mA, with a maximum power dissipation of 13 W. Operating temperature range is 0–60 C, storage temperature from -30 C to 85 C, and humidity range 5% to non-condensing. The faceplate includes a 7-segment fault-code LED and a green OK LED for onboard diagnostics, and the module requires MaxPak III Digital D-C Drive software version 6.1A or higher and the AutoMax DCS environment for proper operation.
