The series 9444/12 power module supplies up to eight IS1+ I/O modules, including the connected field circuits, with intrinsically safe energy. A 24 V DC external power supply is required. The power module can be replaced while the system is in operation and without having to disconnect the power supply (i.e. hot swapped).
- For intrinsically safe IS1+ system supply
- For up to eight IS1+ I/O modules and connected field devices
- Power module hot swap in Zone 1 and Class I, Div. 1
- Use together with 9441/12 CPU and 9492/12 socket
