The Siemens 6AV3515-1MA00 (OP15B) is a robust operator interface terminal engineered for the Simatic S5 automation series. This unit serves as a critical human-machine interface (HMI), enabling operators to monitor process variables, adjust setpoints, and perform real-time diagnostics directly on the factory floor. Designed for reliability in demanding industrial environments, the OP15B provides a clear, configurable display and a durable input interface, making it a standard component for legacy S5-based control systems in sectors such as power generation, petrochemicals, and heavy manufacturing.
The OP15B is widely utilized in legacy automation architectures where direct, reliable interaction with the PLC is required. Typical applications include:
| Model | 6AV3515-1MA00 (OP15B) |
| Brand | Siemens Simatic S5 |
| Display Type | Monochrome LCD |
| Display Modes | 4-line (20 chars/line) or 8-line (40 chars/line) |
| Character Height | 8 mm (4-line) / 4.5 mm (8-line) |
| Input Interface | Sealed membrane keypad |
| Power Supply | 24 VDC |
| Operating Temperature | 0 to 50 deg C |
The 6AV3515-1MA00 is specifically designed for the Simatic S5 ecosystem. Compatibility with S7 systems is generally not supported without specialized protocol conversion hardware.
Maintenance is minimal due to the solid-state design. We recommend periodic inspection of the membrane keypad for wear and ensuring that the rear communication terminals remain free of corrosion and debris.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
