CSL Part Number: 105138
Product Overview: The Entertron SPP/EPP PM05 is a relay-based control board that interfaces inputs from external devices (such as PLCs) to control multiple output relays. It uses optocouplers for input isolation, driver ICs (including ULN2003 Darlington arrays) to energize output relays, and LEDs to indicate relay status. Commonly found in industrial automation equipment like RDN Manufacturing Company cut-to-length auto saws, it operates on 24 VDC and features an 11 MHz clock with onboard voltage regulation providing 5V to internal logic components.
Category: Control Board
Manufacturer: Entertron
Manufacturer Part Number: SPP/EPP PM05
Common Failures
Some units have experienced issues with the relays not energizing, often due to malfunctioning components within the relay driver circuitry. Issues such as a shorted driver chip and intermittent LED connections have been identified, leading to problems in output activation. Specifically, Output 3 not functioning correctly has been a common symptom, often requiring related components such as transistors and LEDs to be replaced.
Repair Approach
Repairs typically involve diagnostic testing to isolate defective components. Key interventions include replacing the driver chip and LEDs associated with the affected outputs. Ensuring proper connection and operation of transistors and relay circuits has been essential in resolving these issues. Components are thoroughly tested after replacement.
Testing & Quality
After repairs, units undergo comprehensive testing. Diagnostic tests are performed to ensure all components function as expected. Burn-in tests are conducted, where relays are activated for extended periods to verify reliability.
