STAHL 9440/15-01-11 Power Module is an intrinsically safe CPU & power module designed for the R. STAHL IS1 Remote I/O system used in industrial , especially in hazardous environments (Zone 2/Division 2, and related hazardous area classifications). It integrates a power supply with fieldbus communication capability, providing intrinsically safe 24 V DC power to up to 16 IS1+ I/O modules and associated field circuits. Communication with the system is achieved via RS-485 fieldbus protocols such as Profibus DP (including V0/V1/HART variants) or Modbus RTU, and the module supports system redundancy and optical ring topologies for high availability.
