Upgrade your S7-300 logic-controlled system by adding this analogue output module from Siemens. As it has a 12-bit resolution and an overage of ±10V and ±20mA, it's suitable for programming with variable-control devices. Four integrated outputs mean you can connect and control multiple functions. Use it with solenoid valves, level indicators and motor starters in industrial processing and material handling applications. The module has a compact width of 40mm and depth of 120mm, making it easier to fit alongside your CPU. It's suitable for installation and removal when the backplane is active, so there's no need to shut your systems down to upgrade them.

• Voltage and short circuit protections to help safeguard your system
• Comes with diagnostic alarms, LEDs and messaging, making it easier to spot problems

Digital output modules control devices that only have two states, such as on and off. An analogue output module controls devices that have more than two states, such as a motor that operates at various speeds.
