Eaton 8526A-6501 Output Relay Module

Description

Eaton 8526A-6501 Output Relay Module

The Eaton 8526A-6501 (also marketed under the Cutler-Hammer brand) is a plug-in DPDT relay output module designed for use with Eaton’s 70 Series photoelectric sensor control units and systems.

Product Detailed Description

The 8526A-6501 serves as an electromechanical switching output card that plugs directly into a compatible Eaton Series 70 modular photoelectric control unit. It receives switching logic from remote sensor heads (such as thru-beam, reflex, diffuse reflective, or fiber optic heads) and drives high-power electrical loads like motor starters, solenoid valves, alarms, or PLC inputs.

Technical Parameters

Product Advantages

• Modular Plug-In Design: Easily inserts into the control chassis without requiring complex rewiring, minimizing downtime during maintenance.
• High Switching Capacity: Dual-pole (DPDT) relay configuration enables simultaneous control of two isolated circuits or high-voltage AC loads up to 5 A.
• Fast Relay Switching: A rapid 7 ms response time ensures dependable tracking in fast-paced industrial detection lines.
• Flexible Sensor Integration: Compatible across the entire Series 70 optical range, including thru-beam, reflex, fiber optic, and slot sensors.

Important Considerations & Precautions

• Load Rating Limits: Ensure the connected electrical load does not exceed 5 A at 230 VAC or 30 VDC. Inductive loads (e.g., motor coils, solenoids) should use surge suppression (RC snubbers or flyback diodes) to prevent contact arcing.
• Control Chassis Requirement: The 8526A-6501 is an output module and requires a compatible Series 70 main control unit chassis to operate; it cannot function as a standalone sensor.
• De-energize Before Installation: Always disconnect main system power before plugging in or removing the module to avoid electric shock or pin damage.
• Environmental Rating: Mount inside an appropriate enclosure if used in dusty, wet, or outdoor environments to protect the relay pin headers.

Product Applications

• Conveyor & Packaging Lines: Switching diverters, stop gates, or alarms based on photoelectric line monitoring.
• Material Handling: Interfacing optical sensors with motor contactors and control relays.
• Factory Automation: Providing relay isolation between field photoelectric sensors and higher-level automation equipment (e.g., PLCs).
