The RELIANCE 57402 (also referred to as 0-57402 or 0-57402-C) is a 16-channel AC/DC low-power digital output module designed for use with AutoMax distributed control systems in industrial automation applications. It converts digital signals from a controller into electrical outputs to drive low-power devices such as relays, solenoids, or indicator lights. Below is a detailed breakdown based on technical specifications and industry documentation:
Output Configuration
- Channels: 16 isolated output circuits with individual LED status indicators (labeled 0–15).
- Output Type: Universal AC/DC (compatible with both AC and DC loads).
- Voltage Range: 24–115 V AC/DC (nominal ratings vary by model; check part suffix for exact specs).
- Current Rating:
- Maximum Continuous Current: 200 mA per channel.
- Maximum Leakage Current (Off State): 1.0 mA.
- Isolation: 2,500 V AC RMS between outputs and logic/common.
Physical & Environmental
- Dimensions: Approximately 233 mm × 160 mm (9.2” × 6.3”).
- Weight: ~1.11 kg (2.45 lbs).
- Operating Temperature: 0°C to 60°C (32°F to 140°F).
- Storage Temperature: -40°C to 85°C (-40°F to 185°F).
- Humidity: 5–90% non-condensing.
Power Supply
- Module Voltage: Derived from the output signal (24–115 V AC/DC).
- Current Consumption: Dependent on load but typically ≤200 mA per channel.
Fault Detection
- LED Indicators: Show channel status (ON/OFF) and fault conditions.
- Error Codes:
- 31: Bus error (module missing, malfunctioning, or in incorrect slot).
- 51–58: Specific communication or configuration errors.
Installation
- Mounting: DIN-rail or panel-mountable via metal brackets on the faceplate.
- Terminals: 16 small male ports (0–15) for outputs and 20 larger ports (0–15) for commons, labeled C1–C4 (4 isolated commons).
- Universal Compatibility: Supports both AC and DC loads, reducing the need for separate modules.
- Isolated Design: Protects against voltage spikes and electromagnetic interference (EMI).
- Compact Form Factor: Space-efficient for rack-mounted control systems.
- Low Power Consumption: Ideal for applications requiring ≤200 mA per channel (e.g., pilot lights, small relay coils).
- LED Diagnostics: Simplifies troubleshooting and status monitoring.
- Industrial Automation: Controlling relays, solenoids, or motor starters in manufacturing lines.
- HVAC Systems: Actuating dampers or valves with low-power signals.
- Building Automation: Powering indicator lights, buzzers, or small sensors.
- Process Control: Interfacing with low-power field devices in chemical or oil/gas plants.
- Manuals:
- AutoMax System Operation Manual (J-2-3104) for integration guidelines.
- Module Installation Guide for wiring and mounting instructions (available through third-party suppliers).
- Certifications: CE, UL, and RoHS compliance (varies by model revision).
- Part Numbers:
- Base: 57402
- Common Variants: 0-57402-C, 0-57402-E (check suffix for voltage/current specifics).
- Discontinuation Status: No longer manufactured by Reliance Electric; available through authorized resellers like AX Control or SAUL DCS.
- Load Limitations: Avoid exceeding 200 mA per channel to prevent damage.
- Wiring: Use shielded cables in high-noise environments to maintain signal integrity.
- Compatibility: Ensure compatibility with your AutoMax controller’s firmware version and power supply 规格.
