ABB 500BOM01 (1MRB150023R0002) – Binary Output Module for ABB 500-platform Drives and Control Cabinets
The ABB 500BOM01 is a binary output module designed for the ABB 500-series control platform, typically used in DC/AC drive systems and related automation cabinets. It provides robust, opto-isolated 24 VDC digital outputs for driving interlocks, relays, contactors, and alarm signaling. From my experience, it’s a straightforward drop-in spare that helps restore I/O functionality without touching the main controller.
If you’re maintaining installed ABB 500-based systems, this module seems to be the safe choice when field outputs start to misfire or you need additional relay points. You might notice that commissioning is usually quick—LED diagnostics and clear terminal labeling make checks easy.
24 VDC binary outputs – Designed to drive field relays, lamps, and contactor coils commonly found in drive panels.
Channel isolation – Opto-isolated outputs help reduce ground loops and electrical noise in mixed-voltage cabinets.
Status LEDs per channel – Quick visual checks during commissioning or fault tracing; typically saves time on site.
Backplane integration – Communicates via the ABB 500 platform backplane; no external gateway needed.
Service-friendly terminals – Pluggable or clearly marked terminals make it easier to replace the board without rewiring the whole strip.
Field-proven design – Built for industrial environments; works reliably in most cabinet temperatures and with inductive loads (with proper suppression).
Direct replacement part – Ordering code 1MRB150023R0002 helps ensure you get the correct board for the 500-series base hardware.
| Brand / Model | ABB 500BOM01 |
| Ordering Code | 1MRB150023R0002 |
| Module Type | Binary Output Module (24 VDC digital outputs) |
| Power Requirements | Backplane powered; field supply typically 24 VDC for output loads |
| Signal I/O Types | Digital outputs (opto-isolated); intended for relays/inductive loads with suppression |
| Communication Interface | ABB 500-series backplane bus (controller-managed) |
| Operating Temperature | Typically 0 to +55 °C; non-condensing environment |
| Installation Method | Plug-in module for ABB 500 platform base hardware/cabinet |
| Dimensions & Weight | Compact plug-in board (verify against cabinet slot type) |
In many cases you’ll see the 500BOM01 in drive and motion cabinets where deterministic on/off signaling is needed. Typical roles include:
DC/AC drive systems (interlocks, run/ready, fault relays, contactor control)
Process automation panels (alarm beacons, solenoid valves via relay interfaces)
Material handling and cranes (limit switches, hoist/brake command relays)
Metals, paper, mining, and marine drive retrofits where ABB 500-platform I/O is standard
Compatibility you can trust – Designed for the ABB 500 platform, reducing integration risk and engineering time.
Stable field performance – Isolated outputs and clear diagnostics typically mean fewer nuisance trips.
Lower lifecycle cost – Replace a single module instead of a whole controller to recover output channels.
Service continuity – Easy swap during planned downtime; wiring remains largely untouched.
Cabinet environment – Mount in a clean, ventilated control cabinet; maintain ambient within typical 0–55 °C and non‑condensing humidity.
Wiring – Use correctly sized conductors for 24 VDC outputs; add suppression (diodes/RC) for inductive loads to extend relay life.
ESD handling – Observe antistatic precautions when inserting or removing the module.
Commissioning – Verify backplane seating, check channel LEDs, and validate output logic in the controller before energizing field devices.
Routine checks – Periodically re-torque terminal screws, inspect for dust buildup, and review event logs for intermittent output faults.
Compatibility note – Match the board’s hardware revision to your controller’s firmware guidelines; this is minor but helps avoid odd behaviors.
CE compliant; RoHS alignment in most shipments for the platform generation
Often supplied with UL recognition at the system level (verify per installation)
Manufacturer warranty: typically 12 months when sourced new; extended or refurbished options vary by channel
Tip from the field: if a few channels show erratic behavior under inductive load, adding proper flyback diodes at the relay coil usually stabilizes things right away.
