Product Description

1.

Product Descriptions :

Order Number: UN 124-2BB23-0XB8  

Local digital Inputs & Outputs: 14DI/10DO,  

Appropriate computering and data processing, external connection with three I/O Expansion modules, long-time data-holding on power-off, 

Unique AES Iterative encryption algorithm,which protects clients' intellectual property,  

Reliable: Compatible with S7-200 software;

2. I/O Expansion: Can connect 3 PCS I/O expansion Modules;
3. Each port (A, B, C, D, E) of the digital input filter can provide a unified input filter delay, the arrange being 1 ms to 31 ms;
4. Digital module: Inputs & outputs apply optical isolation and module filter anti-interference; Highly reliable.
