Overview
Safety Instrumented System SIS, digital output module SM 326F-DO, used for digital output of fault safety SIMATIC S7 system, two models (1 x source/source output, 1 x source/leakage output), used to connect solenoid valves, DC contactors and indicator lights, with safety integration function, for safe operation, and for fault safety mode.
Product Details
Safety Instrumented System SIS Digital Output Module SM 326F-DO
The Safety Instrumented System SIS digital output module SM 326F-DO is divided into two types:
1 SIMATIC S7， Digital output SM 326, F-DO10x 24V DC/2A PP, fault safe digital output for SIMATIC S7F safety instrumented system SIS, with diagnostic alarm, LVV， To Class 4 wire (EN 954-1)/SIL3 (IEC61508)/PLE (ISO13849), one 40 pin, order number: 6ES7326-2BF10-0AB0.
2 SIMATIC S7， Digital output SM 326, F-DO 8xDC 24V/2A PM Fault Safety Instrumented System SIS digital output P-M switch, to Class 4 wire (EN 954-1)/SIL3 (IEC61508)/PLE (ISO13849), one 40 pin, order number: 6ES7326-2BF41-0AB0.
1、 Overview of Safety Instrumented System SIS Digital Output Module SM 326F-DO
Digital output for fault safety SIMATIC S7 system, two models (1 x source/source output, 1 x source/drain output), used to connect solenoid valves, DC contactors, and indicator lights, with safety integration function, for safe operation, and for fault safety mode.
Centralized: equipped with S7-31xF DP, S7-31xF PN/DP; ET200M distributed: equipped with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-41xF-2, and S7-400F/FH.
2、 Application of Safety Instrumented System SIS Digital Output Module SM 326F-DO
The fail safe digital output module is designed for centralized use with SIMATIC S7-31xF-2 DP and can be used with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2, and S7-400F/FH in ET200M distributed I/O stations. These modules are suitable for connecting solenoid valves, DC contactors, and indicator lights.
3、 Design of Safety Instrumented System SIS Digital Output Module SM 326F-DO
The fault-tolerant digital output module has the following mechanical characteristics:;
Compact design;
Each output has two connectors for single channel or redundant actuator control;
Green LED, used to indicate the status of the output signal;
A green LED indicates safe mode;
1 red group fault indicator light;
Plug in device, used for the front connector, protected by the front cover;
Label area on the front cover;
Easy installation;
The installation method is the same as other I/O modules of ET 200M;
User friendly wiring through the front connector.
4、 Safety Instrumented System SIS Digital Output Module SM 326F-DO Function
The fail safe digital output module converts the internal signal level of the fail safe SIMATIC S7 CPU into the external signal level required by the process. The fault safety operations required for safety functions are integrated into the module.
