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

Hook up your measuring devices up to a controller with this Siemens digital I/O module. It connects counting and position-sensing equipment to a PLC, ensuring linked machines stay informed about the flow of objects through the system. By handling object frequencies up to 4MHz, the device easily counts high volumes to keep its process on track. Four inputs and outputs let you link multiple components up at once, which simplifies your setup. As the product's solid state transistor outputs switch in just 50μs, you can be sure it won't be caught napping. I/O modules like this are handy for connecting equipment in warehouses and processing plants.

• Snaps onto a DIN rail without tools, making installation easy
• Short-circuit protection to minimise the risk of hardware damage from power faults
• Regulation RS422 interface for convenient connection to standard networks
• Diagnostic alarm and LED lights draw your attention to faults before they cause trouble

Relay outputs operate a pair of contacts to turn on and off. Solid state outputs, which this module has, switch their circuits using optical signals. This minimises mechanical wear and supports a long service life.
