Description

6ES7323-1BH01-0AA0 is a Siemens SIMATIC S7-300 SM 323 optically isolated digital module with eight digital inputs and eight digital outputs. It operates with a rated 24 V DC load supply, provides a rated output current of 0.5 A per channel, and has a typical power loss of 3.5 W. The module combines input signal acquisition and output switching in one compact S7-300 assembly for streamlined control-cabinet integration. 6ES7323-1BH01-0AA0 supports reliable interfacing between field devices and the automation controller. Its isolated channel groups help maintain clear separation between field circuits and the backplane bus. This Siemens digital I/O module is suitable for replacement, maintenance, and expansion work in compatible SIMATIC S7-300 automation systems.

Functions

- Acquires binary status signals from connected field devices.
- Transfers digital input states to the SIMATIC automation controller.
- Switches connected actuators and signaling devices according to the control program.
- Combines input acquisition and output control within one module position.
- Provides optical isolation between field-side circuits and the backplane bus.
- Supports clear visual monitoring of input and output channel states.
- Protects output channels against short-circuit conditions.
- Enables connection of compatible two-wire sensors.
- Supports redundant control of a load using outputs from the same group.
- Helps simplify maintenance, replacement, and expansion of compatible S7-300 stations.
