Siemens PLC I/O Module, Digital Input Type, 16 Inputs - SIMATIC Series - 6ES7221-1BH32-0XB0
This PLC I/O module from Siemens is designed to increase the range of your SIMATIC S7-1200 programmable logic controller. Use it to build a modular CPU system that meets your specifications with no redundant equipment. It features 16 digital inputs, so you can adapt the controller as needed to various industrial automation, robotics or manufacturing tasks. For flexible operation, it can be connected with both sink and source configurations. Galvanic isolation between digital inputs (in groups of four) allows information transfer while preventing current leakage and protecting your equipment.
• Compact dimensions of 75 (L) x 45 (W) x 100mm (H) saves space on the control panel
• Operating temperature range of -40°C to +70°C for use in challenging environments
• DIN rail mounting enables easy installation
