0-57408 refers to the base model of AutoMax power and drive interface card. Digit 1 stands for the 1st generation hardware. Suffix B indicates minor PCB revision and firmware optimization for better compatibility and communication stability.Full name: Power Module Interface Module for AutoMax / DCS 5000Compatibility: Direct drop-in replacement for 0-57408-1, 0-57408-1A and 0-57408-1C. Fully compatible with 0-57407 CPU series, 57C493 power supply and all standard AutoMax drive modules.

Manufacturer: Reliance Electric, now part of Rockwell AutomationMain function: Isolate and distribute power and control signals among CPU, power module, analog I/O and drive controllerFront panel interfaces: 3 x RS-232 DB9 female ports (TO POWER MODULE, TO ANALOG I/O, TO DRIVE CONTROLLER); 4-position CURRENT CALIBRATION terminal blockOperating voltage: 120 VAC / 24 VDCOperating temperature: 0°C to +60°CIsolation rating: 2500 VAC optical isolation between channelsDimensions: 342 × 205 × 30 mm, standard 1.25 inch slot sizeWeight: Approx. 0.76 kg to 1.0 kgProtection class: IP20, no conformal coatingPower consumption: ≤ 18 W

No LED indicators or digital display. All ports and terminals are clearly labeled.Support hot-swap operation for rack installation and removal.

Central signal routing and galvanic isolation for power, analog and drive control signals inside AutoMax rack.Dedicated terminal block supports on-site current loop calibration for drive systems.Three independent isolated RS-232 ports for reliable serial communication with related modules.Standard backplane design, no adapter required for installation.Enhanced anti-interference performance and communication reliability via PCB layout and firmware upgrade on Revision 1B.Pin-to-pin compatible with earlier revisions, no wiring or program modification needed during replacement.

0-57408-1: Original version, 0°C to +60°C, no conformal coating0-57408-1A: Minor firmware adjustment, same electrical parameters0-57408-1B: PCB and firmware optimized for improved stability and compatibility0-57408-2: Extended temperature range -10°C to +60°C, equipped with conformal coating

Applicable System: Reliance AutoMax / DCS 5000Target Industries: Metallurgy, pulp and paper, water treatment, power generation, general manufacturingMain Usage: Drive system integration, multi-motor control, analog signal conditioning and power module coordination in DCS racks.

Insert the module into vacant slot of AutoMax backplane and fasten the latches. Connect RS-232 cables to corresponding modules and wire the calibration terminals as required.

Check cable connections and mounting latches quarterly. Perform ESD-safe cleaning on panel and connectors every six months.Replacement: All revisions of 0-57408 are fully interchangeable without program changes.
