Product Overview

The Siemens 6AV3607-1JC20-0AX1​ is a legendary operator panel belonging to Siemens’ SIMATIC OP7 series, purpose-engineered as a text-based human-machine interface (HMI) for industrial automation systems built on SIMATIC S7 and M7 controller platforms. As the OP7/DP variant within the 6AV3607 family, the Siemens 6AV3607-1JC20-0AX1​ features a 4-line LC display with LED backlighting, presenting 20 characters per line for clear, unambiguous operator communication in even the most demanding factory environments. This panel represents the gold standard of keypad-operated HMIs, combining a rugged membrane keyboard with 8 function keys (4 of which feature integrated LEDs) to deliver tactile, glove-compatible operation that modern touchscreens often struggle to match in harsh industrial settings.Although Siemens has officially discontinued the Siemens 6AV3607-1JC20-0AX1​ (product lifecycle ended October 1, 2018), the device remains one of the most sought-after spare parts in the global automation aftermarket, as countless machines from the 1990s and 2000s continue to rely on its proven, maintenance-free operation. The Siemens 6AV3607-1JC20-0AX1​ communicates via PROFIBUS DP at up to 1.5 Mbaud, ensuring seamless integration with SIMATIC S7, M7, and SIMATIC S5 controller families, as well as third-party PLCs through optional loadable native drivers for Allen-Bradley DF1, AEG/Modicon Modbus, Mitsubishi FX, and Telemecanique protocols. Powered by a 24 V DC supply drawing just 0.19 A, the Siemens 6AV3607-1JC20-0AX1​ operates without internal batteries—all configuration data is retained in non-volatile flash memory, making the panel truly maintenance-free throughout its operational lifetime.With a front protection rating of IP65 and rear rating of IP20, certifications spanning CE, GL, BV, DNV, LRS, PRS, FM Class I Div.2, UL, CSA, cULus, and ATEX Zone 2/22, the Siemens 6AV3607-1JC20-0AX1​ is qualified for deployment in marine, offshore, hazardous-area, and heavy-industrial environments worldwide. Its compact 144 × 180 × 38.5 mm housing weighs only 0.43 kg, yet delivers enterprise-grade HMI functionality—supporting 99 screens, 256 alarm buffers, 99 recipes with 420 KB recipe memory, 50 password-protected access levels, and multilingual operator interfaces. For plant operators seeking to restore or maintain legacy machinery without undertaking costly full modernization projects, the Siemens 6AV3607-1JC20-0AX1​ remains the definitive spare-part solution.

Main Features and Advantages

The Siemens 6AV3607-1JC20-0AX1​ delivers enduring value to plant operators and machine builders by providing a proven, maintenance-free operator interface that has stood the test of time across decades of industrial deployment. Its defining characteristic is the marriage of a high-readability 4×20 character LC display with a rugged membrane keypad—a combination that excels in environments where gloved operation, vibration, moisture, and dust would render touchscreen-based HMIs unreliable. The Siemens 6AV3607-1JC20-0AX1​ LED backlighting achieves an MTBF of 100,000 hours at 25°C, ensuring years of continuous, flicker-free operation without backlight replacement.Zero-Maintenance Flash Memory Architecture: Unlike contemporary HMIs that depend on batteries for data retention and real-time clock backup, the Siemens 6AV3607-1JC20-0AX1​ stores all configuration, recipes, and operational data in non-volatile flash memory with no battery requirement whatsoever. This battery-free design eliminates a primary failure mode of legacy HMIs, ensuring that the Siemens 6AV3607-1JC20-0AX1​ remains fully functional even after prolonged storage or power loss. The message buffer is retained for several hours after power-down, while the internal hardware clock maintains reserve power for several days—protecting critical time stamps and alarm logs.Exceptional Operator Interface Ergonomics: The Siemens 6AV3607-1JC20-0AX1​ features 8 programmable function keys, 4 of which incorporate multi-color LED indicators for at-a-glance status feedback. Combined with a full alphanumeric membrane keyboard (including hexadecimal input capability) and 22 system keys for navigation, the panel provides operators with comprehensive control authority. The tactile membrane keys offer precise activation with user-definable label strips, enabling machine builders to customize key functions to specific application requirements. This physical button philosophy reduces operator error rates and accelerates response times in time-critical industrial scenarios.Comprehensive Communication Flexibility: The Siemens 6AV3607-1JC20-0AX1​ integrates 1 × RS232, 1 × RS422, and 1 × RS485 interfaces, with the RS485 port dedicated to PROFIBUS DP communication at up to 1.5 Mbaud. This tri-interface architecture enables simultaneous connection to a SIMATIC S7/M7 PLC via PROFIBUS, a computer for project transfer via RS232, and a printer or secondary device via RS422. The Siemens 6AV3607-1JC20-0AX1​ natively supports SIMATIC S5 (AS511, FAP), SIMATIC S7/M7 (PPI, MPI, PROFIBUS DP up to 1.5 Mbaud), and SIMATIC 500/505 (NIT) protocols, with optional loadable native drivers extending compatibility to Allen-Bradley DF1, AEG/Modicon Modbus, Mitsubishi FX, and Telemecanique Adjust/Uni-Telway networks—making the panel a truly universal operator terminal for multi-vendor automation architectures.Enterprise-Grade HMI Functionality: Despite its text-based display, the Siemens 6AV3607-1JC20-0AX1​ delivers SCADA-class capabilities: 99 configurable screens with up to 99 entries per screen and 300 fields per screen, 256-entry alarm message buffer with date/time stamping and acknowledgment tracking, 99 recipes with 420 KB total recipe memory and 99 data records per recipe, 50 password-protected access levels across 9 security tiers, and multilingual operator interface supporting German, English, French, Italian, Spanish, and Russian with online language switching between 3 languages. The Siemens 6AV3607-1JC20-0AX1​ also provides diagnostic functions including STATUS/FORCE VAR monitoring and loop-through operation for configuration computers.Global Certification Portfolio: The Siemens 6AV3607-1JC20-0AX1​ carries an unparalleled array of international certifications—CE for Europe, GL/BV/DNV/LRS/PRS for marine and offshore applications, FM Class I Div.2 for North American hazardous locations, UL/CSA/cULus for North American safety compliance, and ATEX Zone 2/22 for explosive atmosphere deployment. This certification breadth ensures that the Siemens 6AV3607-1JC20-0AX1​ can be deployed in virtually any industrial environment worldwide without additional safety engineering. The IP65 front bezel protects against dust ingress and low-pressure water jets, while the -25°C to +70°C storage temperature range confirms the panel’s resilience to extreme climate conditions during transport and warehousing.
