Rayon Automation offers original, in-stock Siemens 6ES7326-2BF01-0AB0 fail-safe digital output modules. As the core safety component in Siemens S7-300 and ET 200M systems, it is specifically designed for safety circuit control in high-risk industrial environments.
As a supplier, Rayon Automation provides in-stock Siemens 6ES7326-2BF01-0AB0, equipped with 10 independent and potential-isolated digital output channels, featuring a P/P switch structure, with a rated output current of 2A, and complies with safety integrity levels SIL 3 (IEC 61508) and international stringent safety standards such as Cat. 4 / PL e (ISO 13849-1).

The module integrates two independent microprocessors internally, conducting cross-comparison and verification of control instructions for each output channel.
The Siemens 6ES7326-2BF01-0AB0 has comprehensive diagnostic functions, including external 24V power supply absence detection, output channel short circuit, overload, and open circuit detection. The module periodically sends extremely short-duration dark test pulses to the output terminals (Dark Test) to detect whether the output solid-state switches are stuck without affecting the operation of external actuators in real time.
All 10 channels adopt P/P (P-Switching / P-Switching) control mode, cutting off the high potential end of the load in double.
The front panel is equipped with SF (system failure), BF (bus failure), ON (power supply), and green/yellow status indicator lights for each of the 10 channels.
1. Mount the Siemens 6ES7326-2BF01-0AB0 module onto the standard S7-300 rail and secure it with the fixing screws. Ensure that the rail itself has a low-resistance metallic contact with the grounding busbar of the control cabinet.
2. Connect using a 40-pin connector. Introduce the 24V group power supply to the corresponding power input terminals. Connect the load correctly to the corresponding output terminals and ensure that the potential isolation relationship among multiple power supply groups is correct.
3. Add this F-DO module in STEP 7 or TIA Portal, and set the PROFIsafe security address (F-Address) exactly the same as the software configuration on the DIP switch on the side of the module.
4、After the system is powered on for the first time, a safety logic signature verification must be performed in the software, and the emergency stop button on site should be manually triggered to verify whether the output can be cut off within the specified response time.

The box is sealed with standard anti-static shielding bags. High-density shock-absorbing foam is filled inside the box. The outer layer is sealed with thick-walled export-specific cartons. We cooperate closely with international courier companies such as DHL, FedEx, and UPS to provide transportation services under various trade terms. For urgent orders that are temporarily suspended, we can offer an expedited processing channel.



6ES7326-2BF01-0AB0 is a fault-safe (F-DO) module, featuring a dual-processor structure and supporting dark pulse diagnosis and PROFIsafe protocol, and can be used in SIL 3 safety circuits; while the ordinary 322 module is only used for general standard control and does not have safety diagnosis and redundant cut-off functions.
OK. It can be directly inserted onto the main CPU rail of S7-300, or installed on the slave station of ET 200M that has been expanded through the IM 153-2 interface module. It can communicate securely with the main station CPU via PROFIBUS or PROFINET for PROFIsafe purposes.
The modules we deliver are all original MiKua products that have undergone strict physical and electrical tests. They come with a 12-month quality guarantee and are accompanied by a test-outlet invoice with the goods.
