GE IC695PSA040

Description

1.Core Function&Positioning

The GE IC695PSA040 is a critical power supply module within the PACSystems RX3i series,designed to deliver stable,reliable power to industrial control systems.It supports dual-mode input(AC/DC)and provides three regulated DC outputs:

+5.1VDC(8A)for logic modules(e.g.,CPU,communication modules).

+24VDC(2A)for peripheral devices(e.g.,sensors,actuators,relays).

+3.3VDC(internal use)for system-level components.

With a 40W total output capacity,it ensures seamless operation of RX3i-based control architectures in harsh industrial environments.

3.Performance Advantages

3.1 Wide Input Range&Global Compatibility

Handles voltage fluctuations common in industrial grids(e.g.,85VAC in weak grid areas or 264VAC in overvoltage scenarios).

Supports both 50Hz/60Hz AC and DC input,enabling flexible integration with solar,battery,or generator-backed systems.

3.2 High Reliability Under Stress

Thermal Design:Passive cooling with aluminum heatsink ensures stable operation up to 70°C without fans,reducing maintenance needs.

Vibration Resistance:Withstands 5G vibration(per IEC 60068-2-6)and 50G shock(per IEC 60068-2-27),ideal for mobile machinery or seismic-prone regions.

3.3 Intelligent Diagnostics&Safety

LED Status Indicators:

Green(PWR):Normal operation.

Amber(PWR OFF):Input power present but output disabled.

Red(P/S Fault):Internal failure(e.g.,overvoltage,overheating).

Amber(Temp/Overload):Approaching thermal or current limits.

Fault Logging:Stores error codes for post-mortem analysis via GE’s ToolboxST software.

Application Scenarios

4.1 Automotive Manufacturing

Powers digital I/O modules and motion controllers in welding robots,ensuring millisecond-level timing precision for spot welding sequences.

Benefit:Zero downtime due to power instability,reducing scrap rates by 15%.

4.2 Oil&Gas Pipeline Monitoring

Operates in-40°C Arctic environments to supply SCADA systems with stable+24VDC for pressure/flow sensors.

Benefit:10-year MTBF in remote locations,minimizing helicopter maintenance trips.

4.3 Water Treatment Plants

Provides ripple-free+5.1VDC to PLC CPUs controlling pump stations,avoiding false trips caused by voltage spikes.

Benefit:30%reduction in unexpected shutdowns vs.generic power supplies.

Installation&Maintenance Best Practices

5.1 Wiring Guidelines

Use 16AWG(1.5mm²)copper wires for input/output connections.

Terminals support≤6A per pin;distribute high-current loads across multiple terminals.

Install a 10A circuit breaker upstream to protect against short circuits.

5.2 Thermal Management

Maintain≥50mm clearance around the module for airflow.

For cabinet installations,ensure ambient temperature≤50°C(derate output by 2%per°C above 50°C).

5.3 Firmware&Configuration

No user-configurable parameters;outputs are fixed at+5.1VDC/+24VDC/+3.3VDC.

Monitor via RX3i backplane communication(if paired with a CPU module).

Ecosystem Integration

Backplane Compatibility:Works with 5-slot,10-slot,and 15-slot RX3i backplanes(e.g.,IC695CHS005,IC695CHS010).

System Expansion:

Daisy-chain up to 4 IC695PSA040 modules to increase power capacity(auto-load balancing).

Not redundant-capable:For high-availability systems,pair with IC695PSA100(100W redundant module).

Competitive Differentiation

Feature IC695PSA040 Generic Industrial PSU

Input Range 85–264VAC/100–300VDC Typically 100–240VAC
