Siemens 6ES7323-1BL00-0AA0 SIMATIC S7-300 Digital I/O SM 323
The Siemens 6ES7323-1BL00-0AA0 is a SIMATIC S7-300 SM 323 digital input/output module combining 16 digital inputs and 16 digital outputs for 24 V DC industrial automation applications. The inputs are suitable for switches and 2-, 3-, and 4-wire proximity switches, while the transistor outputs can control solenoid valves, DC contactors, and indicator lights at up to 0.5 A per channel. Its 32-channel configuration provides a practical solution for S7-300 systems requiring both field-signal acquisition and actuator control in one module.

Description
The Siemens SIMATIC S7-300 SM 323; DI 16/DO 16xDC 24 V/0.5 A combines 16 digital inputs and 16 digital outputs in a single I/O module. The digital inputs operate from a rated 24 V DC supply and are suitable for switches and 2-, 3-, and 4-wire proximity switches (BEROs). The digital outputs are transistor outputs rated at 0.5 A per channel and are designed for controlling solenoid valves, DC contactors, indicator lights, and similar 24 V DC loads. The inputs are electrically isolated as a group of 16, while the outputs are electrically isolated in groups of eight, providing separation between field circuits and the backplane.
The module supports shielded cable lengths of up to 1,000 m and unshielded cable lengths up to 600 m for field connections. The outputs provide fast switching, with a maximum delay of 100 µs from 0 to 1 and 500 µs from 1 to 0, and support switching frequencies up to 100 Hz for resistive loads. Siemens also specifies inductive shutdown-voltage limitation, individual LED status indication for inputs and outputs, 500 V DC isolation testing, and a 40-pin front connector. The SM 323 is well suited for machine control, production lines, conveyor systems, digital sensor monitoring, actuator control, and general-purpose S7-300 automation installations.
