| PCLD-782 PCLD-782B 16-ch Opto-Isolated Digital Input Board 24-ch Opto-Isolated Digital Input Board Features Compatible with all PC-LabCardTM products with DI channels on either 20-pin flat cable or 50-pin Opto-22 compatible connectors 16 or 24 optically-isolated digital input channels Built-in screw terminals for easy input wiring LEDs indicate input logic status Inputs buffered with voltage comparators Introduction PCLD-782 and PCLD-782B digital input daughterboards feature high-voltage (> 1,500 VDC) optical isolation on all inputs. PCLD-782 provides 16 input channels accessible through one 20-pin flat cable connector, which is standard on most PC-LabCardTM products. The PCLD-782B provides either 16 or 24 channels, depending on what connector you use. The PCLD-782B's 20-pin connector lets you access 16 channels, similar to the PCLD-782, but also provides a 50-pin Opto-22 connector with access to 24 channels. Both cards have onboard screw terminals for easy input wiring. Optically isolated signal conditioning provides isolation between separate channels, as well as between each input channel and the PC. This isolation prevents floating potential and ground loop problems while protecting the input lines from potentially damaging fault conditions.
