Siemens Digital I/O Module, Parameterisable Inputs, 20.4 to 28.8V DC Supply Voltage Range - SIMATIC Series - 6ES7521-1BH00-0AB0
Need to get sensors and your control system on speaking terms? Get information from A to B with this digital I/O module from Siemens. It's used with a PLC from the SIMATIC S7-1500 range to support the transmission and processing of operating signals in your automated equipment. There are 16 inputs, meaning this unit lets you receive and transfer signals from multiple sources. As the inputs are parameterisable, you'll have free rein configuring them to suit your equipment's needs. A built-in diagnostic alarm warns of hazards like a wire break or faults in the supply voltage. You'll find modules like this commonly used in chemical plants and pharmaceutical production facilities.
Features & Benefits
• Minimal power loss of 2.6W, so it's energy-efficient
• Compatible with PROFIBUS and PROFINET protocols for convenient industrial communication
• Integrated reverse-polarity protection prevents damage from faulty wiring
• Rated supply voltage range between 20.4 and 28.8V DC for power-supply flexibility
How can I tell the operating status of this module?
It has integrated LED indicators that turn on and off to show its status, so you can check what it's up to in a flash.
