Availability: In stock
Overview
The Siemens 6ES7231-4HA30-0XB0 SB 1231 Analog Input Signal Board is a compact, high-performance expansion module designed specifically for the SIMATIC S7-1200 PLC series. This board provides a cost-effective and space-saving way to integrate analog signals directly into your S7-1200 CPU, eliminating the need for a separate, larger module.
It is ideal for applications requiring the measurement of a single analog value, such as temperature, pressure, flow rate, or level, ensuring precise monitoring and control in a variety of industrial environments. By attaching directly to the front of the CPU, it maintains the compact footprint that the S7-1200 is known for.
