Need to get your PLC on speaking terms with field devices? This digital I/O module from Siemens makes it simple to connect transmitters, sensors and actuators in automation equipment. If there's a problem, look to the individual channel diagnostics to quickly see which component is having issues. This lets you get your system back up and running in a jiffy. The red and green power LED also speeds up maintenance, as you can monitor the module's status with ease. This handy component has eight inputs that are parameterisable, so you can connect multiple devices with no danger of data interference.

• Broad operating temperature range between -30°C and +60°C to suit harsh environments
• Narrow 15mm width fits easily into busy setups
• Light 28g weight won't place strain on your system
• Diagnostic alarm immediately alerts you to issues for faster repairs

If it's shielded, the cable can be up to 1,000m long. If unshielded, it can be up to 600m long. This means you can link up devices across large industrial spaces.
