ABB Jokab Safety Pluto B20 safety controllers are widely utilized to monitor and evaluate safety devices across complex machinery and production lines, including emergency stop buttons, safety light curtains, interlocking guards, and Eden sensors.
Continuous 24/7 operation in control cabinets can eventually lead to thermal degradation of internal power supplies, relay contact pitting, input stage failures, or communication transceivers breakdown. Faults usually trigger an Error LED indicator, bus communication timeouts, or failure to energize output channels.
What we repair on Pluto B20 safety controllers:
-
Internal Power Supply Unit: Board-level repair of internal SMPS circuits, replacement of dried-out capacitors, voltage regulators, and surge protection elements.
-
Safety Relay Outputs: Replacement of pitted, worn, or welded internal output relays using genuine force-guided safety relays.
-
Fail-Safe Inputs & Transistor Outputs: Component-level repair of dual-channel safety inputs, pulse outputs, and solid-state safety outputs.
-
Pluto Bus & RS232 Communications: Servicing of CAN-based Pluto Bus driver ICs, optocouplers, and serial programming port interfaces.
Benefits of our repair service:
-
Preserve Program & Setup: Hardware repair aims to maintain stored safety logic programs and network node parameters intact.
-
Zero Cabinet Modification: Direct plug-and-play reinstallation with no DIN-rail restructuring or wire harness changes.
-
Preventive Component Overhaul: High-stress capacitors and power components are replaced alongside the main repair to ensure long-term operational integrity.
