6ES7326-1RF01-0AB0 Siemens SIMATIC S7 Digital Input SM 326 Original Brand New

• Digital inputs for the fail-safe SIMATIC S7 systems
• For connecting:
  • Switches and 2-wire proximity switches
  • Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas
• With integral safety functions for fail-safe operation
• Can be used in fail-safe operation
  • Centrally: with S7-31xF-2 DP
  • Distributed in ET 200M: with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH
• In standard operation can be used in the same way as S7-300 modules

Fail-safe digital input modules are suitable for connecting

• Switches and 2-wire proximity switches (BEROs)
• Encoders according to NAMUR and mechanical contacts, also for signals from hazardous areas

The modules are implemented centrally with SIMATIC S7-31xF-2 DP, and in the ET 200M distributed I/O module in combination with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH. They can also be used in non-safety-relevant standard mode. In this case, they behave like standard S7-300 modules.

The fail-safe digital input modules feature the following mechanical characteristics:

• Compact design:
  The rugged plastic enclosure contains:
  • Green LEDs for displaying the signal status at the inputs
  • Green LED for indicating safety operation
  • Red LED for group error display
  • Socket 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 ET 200M I/O modules
• User-friendly wiring via the front connector

Note:

Cable guide 6ES7 393-4AA10-0AA0 is required for operation of the 6ES7 326-1RF00-0AB0 fail-safe digital input module in hazardous areas.

Fail-safe digital input modules convert the levels of the external digital signals from the process to the internal signal level of the fail-safe SIMATIC S7 CPUs.
