The ABB 500PB101 1MRB178009R0001 1MRB200064/C is a high-precision low-voltage protection relay module designed for industrial automation systems, serving as a critical component in motor control centers (MCCs) and process control panels. As part of ABB’s Tmax XT series, this module combines advanced timing capabilities with rugged hardware to deliver reliable time-based switching for motors, pumps, and conveyor systems. The ABB 500PB101 is engineered to manage start/stop sequences, duty cycles, and safety interlocks in harsh industrial environments, ensuring precise coordination between field devices and control systems.
Featuring a compact DIN rail-mountable design, the ABB 500PB101 supports multiple timing modes, including On-Delay (TON), Off-Delay (TOFF), and Interval Timer (IT), with adjustable time ranges from 0.1 seconds to 100 hours. Its wide voltage compatibility (24–240 V AC/DC) and reinforced electrical isolation (2.5 kV AC) make it suitable for diverse applications, from automotive manufacturing to water treatment plants. The module’s intuitive front-panel controls and pluggable terminal blocks simplify installation and configuration, while built-in diagnostics enhance system reliability by alerting operators to faults such as open circuits or voltage anomalies.
Flexible Timing Configurations: The ABB 500PB101 offers five programmable timing modes, allowing users to select On-Delay for synchronized motor startups, Off-Delay for post-fault purge cycles, or Interval Timer for energy-efficient duty cycling. A food packaging plant leveraged the Star-Delta (SD) mode to reduce inrush currents in large motors, extending equipment lifespan by 20% while cutting energy costs by 15%.
Rugged Industrial Design: Built with a reinforced thermoplastic housing and gold-plated contacts, the module withstands high vibration (5 g peak) and humidity (95% RH non-condensing), making it ideal for harsh environments like offshore platforms or steel mills. Its IP20 rating and surge protection (4 kV) ensure immunity to electromagnetic interference (EMI), as demonstrated in a chemical plant where the ABB 500PB101 operated flawlessly for five years without failure in a high-EMI reactor control room.
Ease of Integration and Adjustment: The module’s plug-and-play design reduces installation time by 50% compared to programmable logic controllers (PLCs) in basic timing applications. Front-panel dials enable quick adjustment of time settings, the while LED indicators provide real-time status updates. A small-scale manufacturing facility used these features to reconfigure a conveyor’s stop delay from 5 to 30 seconds during product changeovers, enhancing operational agility without downtime.
Manufacturing and Assembly: In automotive plants, the ABB 500PB101 optimizes production line efficiency by controlling robotic cell sequences. For example, it uses Off-Delay mode to keep conveyor belts running for 10 seconds after a fault, allowing residual products to clear the line and minimizing waste. A pharmaceutical bottling line employs Interval Timer mode to cycle pumps on/off at precise intervals, ensuring consistent liquid dosing and reducing quality control deviations by 25%.
Process Industries: In petrochemical refineries, the module manages safety interlocks for valves and pumps. During emergencies, its Single Shot mode triggers a 5-minute purge cycle in reactors before restarting, reducing explosive gas accumulation risks. A water treatment plant uses On-Delay mode to synchronize pump startups with reservoir level sensors, preventing dry running and extending pump life by 30%.
Building Automation: For HVAC systems in commercial buildings, the ABB 500PB101 controls fan duty cycles using Interval Timer mode, balancing ventilation with energy savings. In data centers, it ensures seamless transfer between utility and backup power by managing transfer switch timing, maintaining 99.99% uptime during grid fluctuations.

- ABB TA25DU: A thermal overload relay that pairs with the 500PB101 to protect motors from overheating, ideal for conveyor systems in mining operations.
- ABB AF145-30-11: A three-phase contactor compatible with the 500PB101, enabling timed switching of high-power motors in industrial pumps.
- ABB PTU01: A plug-in time unit extender for the 500PB101, increasing the maximum timing range to 1000 hours for batch processing applications in food manufacturing.
- ABB S200 Series Circuit Breakers: Provide electrical isolation for the 500PB101 in control panels, enhancing safety in high-voltage environments.
Installation Preparation: Mount the ABB 500PB101 on a grounded DIN rail in a control cabinet, ensuring 20 mm clearance for heat dissipation. Use stranded or solid wires (max 2.5 mm²) for power and load connections, tightening terminals to 2–4 Nm torque. Verify voltage compatibility (24–240 V AC/DC) and select the desired timing mode via the front-panel switch before powering up. Avoid installing near high-power cables to minimize EMI interference.
Maintenance Suggestions: Inspect terminal connections biannually for corrosion, especially in humid environments, and clean the module with a dry cloth to remove dust. Use the LED indicators to monitor power and status; a flashing red light signals a fault requiring contact inspection. Replace worn contacts promptly using the module’s pluggable design to avoid downtime. ABB’s predictive maintenance tools can monitor switching frequency and contact wear remotely, enabling proactive replacements and reducing unplanned outages by 40%.
