6ES7288-2QT16-0AA0 Plc Siemens S7-200 Module 8 Channels 24V DC

2. Key Selling Points

1. S7-200 SMART Digital I/O Combination Module:Model EM 288 DI8/DQ8 Relay, provides 8 digital inputs + 8 relay outputs—ideal for small automation systems requiring simultaneous I/O expansion.

2. 8 Channels of 24 V DC Digital Inputs (DI):Input voltage: 24 V DC, supports both sinking (NPN) and sourcing (PNP) wiring (selected via jumper).Compatible with common field devices such as proximity switches, pushbuttons, and sensors.

3. Galvanic Isolation for High Noise Immunity:Optical isolation between input/output channels and between module and CPU—prevents electrical noise and surges, enhancing system stability.

4. Fully Compatible with S7-200 SMART System:Works with popular CPUs such as SR20, ST30, CR40, etc.Up to 7 signal modules can be expanded—enabling compact control systems with hundreds of I/O points.

5. High Reliability & Long Service Life:Relay mechanical life: up to 10,000,000 operations; electrical life: 100,000 operations @ 2 A—ideal for moderate-frequency switching

6. Cost-Effective and Space-Saving:Combines DI and DQ functions in one module—reduces module count and saves panel space.More economical than purchasing separate DI and DQ modules—lowers overall system cost.
