Product Overview

Model Definition

Technical Parameters

• Signal Capacity: 32 digital input points

• Signal Voltage: 5–24 VDC

• Construction: Multi-conductor, shielded cable for EMC noise immunity

• Operating Temperature: 0°C to 60°C

• Connectors: Keyed proprietary card-side connector; field-side flying leads or terminal interface

• Length: Standard factory length (custom lengths optional)

• Weight: Approximately 1.4 kg

Interface and Communication Configuration

• Card Interface: Keyed, latching connector mates directly with 57C404 or compatible 32-point digital input cards

• Field Interface: 32 individual conductors for connection to terminal blocks or field devices

• Shielding: Overall cable shield connected to panel ground for noise reduction

• No network ports; passive signal-only cable

Core Functions

• Transmits 32 channels of digital input signals between field devices and AutoMax input cards

• Simplifies high-density I/O wiring with a single preassembled cable

• Reduces installation time and wiring errors via keyed connectors

• Ensures noise-immune signal transmission for critical on/off sensors and switches

Application Scenarios

• AutoMax system control panels with 32-point digital input cards (57C404)

• Industrial automation requiring high-density discrete input monitoring: conveyor systems, packaging lines, machine tools

• Heavy industries: steel, pulp and paper, power generation, chemical processing

• Cabinet-mounted I/O stations with large numbers of digital sensors, limit switches, and pushbuttons

Operation and Maintenance Instructions

• Power off the system before installation

• Align keyed connector with the input card port and insert firmly; avoid forced insertion

• Route cable separately from high-power AC cables to minimize interference

• Secure cable with clamps to avoid stress on connectors

• Keep connectors clean and dry; inspect periodically for loose wires, damaged insulation, or corrosion

• Replace only with original 57C375 assembly to maintain signal integrity and system compatibility
