Isolated/Relay Digital I/O Terminal

Isolated digital I/O terminals boards and I/O wiring boards offer isolated input channels. The I/O terminals also feature high-voltage protection.

PCLD-782

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-LabCard™ 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.

PCLD-785

The PCLD-785 carries 16/24 SPDT electromechanical relays with a 20-pin flat cable connector and an additional 50-pin Opto-22 connector (for PCLD-785B only) compatible with the digital outputs of most I/O Cards. The number of output channels available on the PCLD-785B depends on the connector you use. The I/O card’s 50-pin connector accesses all 24 channels, while its 20-pin connector has access to 16 channels.
PCLD-785B

The PCLD-785B carry 16/24 SPDT electromechanical relays with a 20-pin flat cable connector and an additional 50-pin Opto-22 connector (for PCLD-785B only) compatible with the digital outputs of most I/O Cards. The number of output channels available on the PCLD-785B depends on the connector you use. The I/O card’s 50-pin connector accesses all 24 channels, while its 20-pin connector has access to 16 channels. The PCLD-785B automatically selects the correct control logic for the connector in use.
