Key Features:

These modules provide up to six channels of analog output. Multi-range outputs support a wide variety of industrial devices. They can drive displays and recorders, control drives, or send analog signals to other systems.
High-resolution, low noise, D/A converters deliver high accuracy and reliability.
3-way isolation further improves system performance.

• StandardProfibus-DP network communication with industry-standardASIC (Siemens SPC3)
• 6-input stand-alone module has much lower start-up cost than multi-piece block I/O systems
• Universal DC outputs support a wide variety of signals and industrial devices
• Three selectable failsafe modes (0%, last-state, or pre-defined) help prevent unsafe conditions
• Compact packaging with pluggable terminals saves space and simplifies wiring
• Wide operational temperaturerange permits installation in extreme environments
