6ES7321-1FF01-0AA0 Siemens Simatic S7-300 Digital I/O Module

Core parameters

Input points: 32 channels, divided into 2 groups with 16 channels in each group

Rated input voltage: AC 120V / 230V (Compatible with two voltage specifications, suitable for different regional power usage standards)

Signal "0" voltage range: 0 to 50V AC (120V specification); 0-100V AC (230V specification)

Signal "1" Voltage range: 70-150V AC (120V specification); 165-264V AC (230V specification)

Input delay: Default 12ms (can be set to 25ms, 50ms, or 100ms through software to enhance anti-interference capability)

Isolation level: Electrical isolation between groups (each group is also isolated from the backplane bus), isolation voltage 250V AC

Operating temperature: 0 to 60℃

Power consumption: Typical value is approximately 8W, and the maximum backplane bus current is 150mA (5V DC)

Functional features

Wide voltage compatibility: Supports two inputs, AC 120V and AC 230V, and can adapt to industrial power supply environments in different countries/regions without the need to replace modules.

Group isolation protection: Two groups of channels are independently isolated, which can prevent the failure of one group of signals from affecting the entire system and at the same time reduce the impact of external AC interference on the controller.

Adjustable filter delay: 4 levels of input delay are available for selection, which can be flexibly set according to the on-site electromagnetic environment, effectively filtering out noise interference in AC signals.

High integration: The 32-channel design saves rack space and supports hot plugging (requiring the S7-300 active bus module), eliminating the need to shut down the machine during maintenance.

Application scenarios

High-voltage equipment monitoring: Signals of AC 220V/110V equipment connected to industrial sites, such as the start-stop feedback of AC motors and the on-off status of high-pressure valves.

Building strong current system: It is used for monitoring strong current equipment in large buildings such as shopping malls and factories, such as air conditioning hosts, main lighting switches, and signal collection of elevator operation status.

Adaptation to traditional industrial equipment: Connect to sensors (such as AC proximity switches), buttons or limit switches that use AC signals in old production lines to achieve digital signal collection.

Cross-regional project deployment: As it is compatible with two AC voltages, it is suitable for cross-border projects. There is no need to purchase modules separately for different regions, reducing supply chain costs.
