Siemens SM 1222 Series Digital I/O Module for Use with S7-300 Series, Digital, Digital, 24 V

For the fault-free flow of information to and from your S7-300 PLC, pick this digital I/O module from Siemens. Thanks to its eight inputs and eight outputs, the unit accommodates multiple circuits to streamline your setup. Time-control functions let you schedule tasks to meet your system's demands. A maximum 500μs output delay means you can be sure of the instant responses needed to keep things ticking along efficiently. Internal short-circuit protection prevents damage and nuisance downtime. This compact device, measuring just 40 (W) x 125 (H) x 120mm (D), is a sure fit in tight spots. When installed horizontally, it works reliably in temperatures up to +60°C.

• 500V DC isolation between the inputs and outputs boosts electrical safety and prevents damage
• 24V DC voltage supply means you can connect it to standard power sources
• Tipping the scales at just 220g, the unit adds minimal strain to your system

This unit performs reliably when used with a shielded 1,000m or unshielded 600m cable. This means you can easily reach devices that are positioned far apart and still get clear signal transmissions.
