Overview
- Digital inputs for the fail-safe SIPLUS 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
Note:
SIPLUS extreme products are based on SIMATIC standard products. The contents listed here were taken from the respective standard products. SIPLUS extreme-specific information was added.
Application
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.
Design
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.
Function
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.
The safety functions required for fail-safe operation are integrated in the modules.
