Daughter Board 16 kênh đầu vào cách ly 2 hướng (Bi-direction) ICP DAS DB-16P
The DB-16P is a 16 channel isolated digital input daughter board forA-82X board or any 812pg,711 726 , 720 series board, and PCI-Bus Multi-function board.
The optically isolated inputs of the DB-16P consists of a bi-directional OPTO-coupler with a resistor for current sensing. You can use the DB-16P to sense DC signal from TTL levels up to 24V. You can also use DB-16P to sense a wide range of AC signals. You can use the board to isolated the computer from large common-mode voltages, ground loops and voltage spikes that often occur in industrial environments.
