The most important function of NNI 16 is the capability to concentrate up to four active current loop lines in one passive Current Loop line. Thanks to this module the numerous industrial systems that use Current Loop standard can be connected together without any problems for communication lines power supply.

The main features of NNI 16 module are:

• - concentrates 4 active Current Loop lines in 1 passive Current Loop line;
• - active Current Loop lines that can be connected up to 4 devices provided of passive Current Loop;
• - management of communication in full duplex modality;
• - maximum baud rate supported by Current Loop line: 19200 Baud;
• - single power supply from mains at 230 Vac or 110 Vac;
• - internal power supply section that ensures the nominal current value by changing the power supply voltage of Current Loop line;
• - current mantained on Current Loop line: 20 mA;
• - one quick release, screw terminal connector for power supply;
• - one quick release, screw terminal connector for passive Current Loop serial line;
• - two quick release, screw terminal connector for active Current Loop serial lines;
• - eight status LEDs that show the activity on active Current Loop serial lines;
• - handy plastic container for a direct mounting on table or electric panel;
• - small dimension: 165 x 90 x 70 mm;
• - weight: 580 g.
