Features:
- 16-channel inputs: accepts no-voltage contact signals with module isolation
- Redundant operation: supports dual-redundant module configuration
- S63 environment: includes a signal cable interface adapter and ISA Standard G3 protection
The SDV144-S63 S4 configuration is a standard ProSafe-RS digital input module with no explosion protection and the G3 environmental option.
It acquires field contact states for safety logic and provides a maximum input response time of 40 ms.
Use the documented 24 V DC external supply, signal cable interface adapter, and compatible dedicated cable when planning the installation.
Availability is subject to Apter Power inventory and sourcing confirmation.
