Product Overview

Model Definition

• RELIANCE: Brand (Reliance Electric, now part of ABB).

• 57C: AutoMax system/I/O series.

• 417: Model code for the AutoMate Interface Module.

  Compatible with standard AutoMax racks and firmware.

Technical Parameters

• Power: +5V @ 2.5A; +12V @ 0.053A (backplane‑supplied).

• Communication: RS‑232 physical layer; AutoMate protocol; AutoMate 40E register mapping.

• Operating Temperature: 0°C to 60°C.

• Humidity: 5%–90% non‑condensing.

• Indicators: 7‑segment LED (fault codes); green OK LED (status).

• Configuration: Front‑panel DROP NUMBER thumbwheel switch.

• Mounting: Single‑slot AutoMax rack (any non‑processor/non‑common‑memory slot).

Interface & Communication

• Rear: AutoMax backplane connector (power + internal bus).

• Front: RS‑232 port for connection to AutoMate PLCs.

• Function: Bidirectional protocol conversion between AutoMax internal bus and AutoMate PLC protocol; data mapping via dual‑port memory.

Core Functions

• Connects AutoMax controllers to Reliance AutoMate PLCs.

• Enables high‑speed, reliable bidirectional data exchange.

• Supports up to four processor interfaces via dual‑port memory.

• Provides real‑time status and fault diagnostics via LEDs.

• Simplifies network node addressing via drop‑number setting.

Application Scenarios

• Industrial automation lines (metallurgy, paper, chemical, power, machinery).

• AutoMax–AutoMate integrated control systems.

• Retrofits of legacy Reliance Electric equipment.

• Distributed control networks requiring cross‑platform PLC communication.

Operation & Maintenance

• Installation: Power off rack; insert into empty slot; secure backplane connection.

• Configuration: Set drop number via front thumbwheel; configure RS‑232 parameters (baud, parity) in AutoMax software.

• Maintenance: Keep RS‑232 port clean; monitor OK LED and fault codes; replace with identical model if failed.

• Warnings: Do not disassemble; avoid moisture/dust; ensure proper grounding.
