The Siemens 6ES7326-2BF10-0AB0 is a highly reliable fail-safe digital output module from the SIMATIC S7 product family. Specifically engineered for safety-related automation tasks, this SM 326 module delivers ten digital outputs, each rated at 24 V DC and 2 A. It is perfectly suited for applications requiring the highest safety integrity levels, such as emergency stop circuits, machine guarding, and process safety systems. For instance, this module is certified for SIL3 according to IEC 61508, Category 4 per EN 954-1, and Performance Level e per ISO 13849-1.
The F-DO10x module offers ten digital outputs with short-circuit protection, ensuring robust operation even in demanding industrial environments. Each output can handle a rated current of 2 A, with a permissible range from 7 mA to 2.4 A across the entire temperature range of 0 to 60 °C. Furthermore, the switching frequency is up to 25 Hz for resistive and inductive loads, and 10 Hz for lamp loads with a maximum of 5 W. Additionally, the output voltage for a signal "1" is at least L+ (-1.0 V), while the residual current for signal "0" is a mere 0.5 mA maximum.
The 6ES7326-2BF10-0AB0 meets the most stringent safety standards, including DIN VDE 0801 AK 5 and 6, EN 954 Cat. 4, ISO 13849-1 PLe, and IEC 61508 SIL3. This module comes equipped with a diagnostic alarm function, and its diagnostic information is readable. Moreover, it features several LED indicators for status monitoring, including a red group error (SF) LED and a fail-safe operation LED. Consequently, troubleshooting becomes significantly more efficient.
This safety module requires multiple power supplies for operation. It draws a maximum of 100 mA from the 1L+ supply voltage (24 V DC) and another 100 mA from the 2L+ and 3L+ load voltages without load. Additionally, it consumes a maximum of 100 mA from the backplane bus at 5 V DC. The typical power loss is 6 W, which should be factored into the cabinet's thermal management.
The total current per output group depends heavily on the installation orientation. For horizontal installation, the maximum total current is 10 A up to 40 °C and 6 A up to 60 °C. Conversely, for vertical installation, the maximum is 5 A up to 40 °C. This distinction is crucial for proper heat dissipation and system longevity. The module also supports cable lengths up to 1,000 m shielded and 600 m unshielded, offering flexibility in system layout.
The module has a compact design, measuring 40 mm in width, 125 mm in height, and 120 mm in depth. It weighs approximately 330 grams, making it a lightweight addition to any S7-300 rack system.
Installing the SIMATIC S7 F-DO10x is straightforward. It mounts onto a standard S7-300 rail within a rack. The module requires a 40-pin front connector for wiring, which is ordered separately. Furthermore, potential separation exists between the channels, with groups of five channels isolated from each other, as well as from the backplane bus and the power supply.
When integrating this fail-safe module into a safety system, ensure that the safety program is correctly configured within the F-CPU. The module's diagnostic capabilities should be fully utilized to monitor the health of the outputs. Additionally, regular testing of the safety functions is recommended to maintain the required safety integrity level.
