SIEMENS S7-300 SM 326 F digital output modules – Safety Integrated
SM 326 F digital output modules – Safety Integrated
Digital outputs for the fail-safe SIMATIC S7 systems
Two versions (1 x current sourcing, 1 x current sinking)
For connecting solenoid valves, DC contactors and indicator lights
With integral safety functions for fail-safe operation
Can be used in fail-safe operation
Centrally: with S7-31xF DP, S7-31xF PN/DP
Distributed in ET 200M: with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-41xF-2 and S7-400F/FH
Fail-safe digital output modules are used centrally with SIMATIC S7-31xF-2 DP, and in the ET 200M distributed I/O device together with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH.
The modules are, for example, suitable for connecting solenoid valves, DC contactors and indicator lights.
In the case of the SM 326 F-DO 10 x DC 24V/2A PP (6ES7 326-2BF10-0AB0), the function “Keep last valid value” can be used optionally in safety mode too. Together with the diagnostics capability of the module, this can be used for cost-optimized implementation of applications in, for example, the area of fire and gas alarm systems (in accordance with EN 54-2/-4 or NFPA72).
Fail-safe digital output modules have the following mechanical features:
2 connections per output for single-channel or redundant actuator control
Green LEDs for indicating signal states at the outputs
Green LED for indicating safety operation
Red LED for group error display
Connection options for the front connector, protected behind the front door
Labeling field on the front door
Simple installation: installation is the same as for the other I/O modules of the ET 200M
User-friendly wiring via the front connector
SM 326 F-DO 10 x DC 24V/2A PP (6ES7 326-2BF10-0AB0) single-width (40mm)
SM 326 F-DO 8 x DC 24V/2A PM (6ES7 326-2BF41-0AB0) double-width (80 mm)
Failsafe digital output modules convert the internal signal level of the failsafe SIMATIC S7 CPUs into the external signal levels required for the process. The safety functions required for failsafe operation are integrated in the modules.
