Product Details
125840-02 is specifically designed for the 3500 series and features:
Compatible with modules such as 3500/40, 3500/42, 3500/22
Supports system-level communication and data interaction
Can be integrated into DCS, PLC, and SCADA systems
125840-02 can convert the input alternating current into multiple stable output voltages, which power the system's internal modules and support the power supplies for I/O and monitoring modules.
This Low Voltage AC Power Input Module can operate stably in harsh industrial environments:
Operating temperature: -30°C to +65°C
Storage temperature: -40°C to +85°C
Humidity: Up to 95%

Q & A
Q: Where is the installation position of the back module?
A: Installed in the designated power slot on the left side of the 3500 rack, it is designed as a half-height module structure.
Q: Is it possible to replace the module while it is powered on?
A: Under the dual-power redundancy configuration, it supports online replacement without affecting the system operation.
Q: How to determine whether a module is functioning properly?
A: The operating status can be determined by the LED indicator lights on the module (such as "Supply OK").
