The Siemens 6ES7231-7PB22-0XA0 is a high-performance analogue input module from the renowned SIMATIC S7 series. This module is specifically designed for S7-22X CPUs and offers two analogue inputs. It is compatible with a wide range of resistance thermometers including Pt100, Pt200, Pt500, Pt1000, Pt10000, Ni100, Ni120, Ni1000, and Cu10.
The module also supports resistors within the range of 0 to 600 ohms. It has a maximum input current of 60 mA from load voltage L+ (without load) and 87 mA from the backplane bus 5 V DC. The power loss is typically 1.8 W, making it an energy-efficient choice for your PLC system.
The 6ES7231-7PB22-0XA0 module uses the Sigma Delta measurement principle and offers a resolution with overrange of 16 bits, providing precise and reliable data. It also features a fast updating time of 405 ms for all channels, or 700 ms when used with Pt10000.
This module does not support plug-in I/O terminals, ensuring a secure and stable connection. It measures 71.2 mm in width, 80 mm in height, and 62 mm in depth, and weighs approximately 210 g.
The Siemens 6ES7231-7PB22-0XA0 is a robust and reliable choice for your PLC system, offering precise analogue input functionality and compatibility with a wide range of resistance thermometers and resistors.
