Description
Product Overview
The RELIANCE 57C370 is a digital terminal strip assembly designed for the AutoMax/Automate system, often branded under Baldor-Reliance or ABB. It serves as a dedicated multi-conductor cable and terminal strip kit, providing a reliable field wiring interface for the 57C400 digital input card. It converts the card’s proprietary faceplate connector signals into standard screw-terminal connections for easy field wiring in industrial control panels.
Model Definition
RELIANCE is the industrial control brand. 57C denotes the AutoMax system I/O and accessory series. 370 identifies a digital terminal strip assembly for 57C400 input cards. No suffix indicates a standard factory version.
Technical Parameters
Constructed with high-grade copper alloy terminals for conductivity and thermoplastic elastomer insulation for durability. Terminal spacing is 2.54 mm for standard wiring compatibility. Operating temperature ranges from 0°C to 60°C, suitable for industrial environments. The assembly includes a keyed multi-conductor cable to prevent misconnection. Voltage and current ratings match the 57C400 input card’s digital signal specifications.
Interface and Communication Configuration
One end features a keyed proprietary connector that plugs directly into the 57C400 input card’s faceplate port. The other end terminates in a screw-terminal strip for field device wiring. No network or communication ports; it is a passive wiring adapter for digital I/O signals.
Core Functions
Transmits digital input signals between field devices and the 57C400 card securely. Provides a convenient screw-terminal interface for field wiring, simplifying installation and maintenance. Uses keyed connectors to avoid insertion errors and protect equipment. Ensures stable and interference-resistant signal transmission in industrial environments.
Application Scenarios
Used in AutoMax/Automate system control panels, specifically with 57C400 digital input cards. Ideal for industrial automation applications requiring reliable digital signal wiring, such as steel, pulp and paper, power, and chemical industries. Suitable for cabinet-mounted I/O stations with field-side digital sensors and switches.
Operation and Maintenance Instructions
Before installation, power off the system. Align the keyed connector with the 57C400 card port and insert firmly. Connect field wires to the terminal strip following polarity and signal assignments. Keep the assembly clean and dry, away from dust, moisture, and corrosive substances. Inspect cables and terminals periodically for looseness, wear, or damage. Do not force connections; if fitting is difficult, verify compatibility. Replace with the same model if damaged to maintain system integrity.
