R. STAHL Remote I/O IS1+ Zone 2 Power Module 9445/35-12
Article Number: 9445/35-12
Art. No.: 315833
Overview and Features
The R. STAHL 9445/35-12 is a 24 V DC supply module designed for the IS1+ Remote I/O system, specifically for Zone 2 hazardous areas. It serves as a power module for IS1+ CPU modules and up to 16 I/O modules.
Key Features:
- 24 V DC supply module for IS1+ CPU modules and 16 I/O modules.
- Redundancy of the power module with load sharing is possible.
- Integrated polarity reversal protection.
- Provides error messages in accordance with NE 107, indicating overload, excess temperature, and maintenance requirements.
- Supports FDT/DTM, OPC UA, and Webserver for integration into asset management systems.
- Extended ambient temperature range from -40 °C to +75 °C (-40 °F to +167 °F).
The 9445/35 power module is used for intrinsically safe power supply to the 9442/35 CPU and up to 16 I/O modules. It can be connected to a 9496/35 base to provide a redundant power supply for the CPU and I/O modules when two 9445/35 modules are used. The module monitors itself and reports notifications to the control system and asset management systems regarding overload, high ambient temperatures, or end of service life.
