Siemens SIMATIC S7-1500 ET 200 Series Digital I/O Module, Digital

This digital I/O (input/output) module from Siemens is an accessory for your PLC (programmable logic controller) that enhances its control capabilities. A PLC sends precise commands to machines and monitors their functions to ensure they work efficiently. The I/O module acts as an intermediary between the CPU (central processing unit) and the processing controls, converting data so communication between them is understood. This I/O module has 32 inputs in 2 rows, so it can connect multiple machines. This makes it a smart choice for use in robotics systems, pharmaceutical production and vehicle manufacturing.

• LED display provides diagnostics, showing green when running and red when there's an error
• Ambient temperature range between 0°C and +40°C (vertically) or +60°C (horizontally) for use in demanding industrial conditions
• Slim shape with 147 (H) x 35 (W) x 129mm (D) dimensions to save space in your setup

The difference between digital and analogue inputs is that an analogue input receives signals with a varying value, whereas a digital input receives signals with a constantly static value.
