Description
The Siemens 6ES7223-1PL32-0XB0 is a digital signal module for the SIMATIC S7-1200 controller platform, expanding a CPU's onboard I/O with 16 digital inputs and 16 relay outputs. It suits machine and process control applications where a single module must read sensor signals and drive a mix of AC and DC actuators. The 24 V DC sink/source inputs follow IEC 61131 type 1, accepting field signals from common industrial sensors and switches.
Each of the 16 relay outputs switches up to 2 A and operates from 5 to 30 V DC or 5 to 250 V AC, rated for 10 million mechanical cycles. The module draws a 24 V DC supply power with a typical 10 W loss and connects through a required front connector. Its plastic enclosure carries an IP20 rating, measures 70 by 100 by 75 mm, and includes LED diagnostics for input and output status.
Frequently Asked Questions
What controllers is the 6ES7223-1PL32-0XB0 compatible with?
