March 1, 2005
The PCLD-8751 and PCLD-8761 are external isolation I/O modules. The PCLD- 8751 has 48 isolated digital input channels, while the PCLD-8761 has 24 relay channels and 24 isolated digital input channels.

The PCLD-8751 and PCLD-8761are designed to make connection with the PCI-1751 and PCI-1753 TTL-level digital I/O boards directly. The PCLD-8751 and PCLD-8761are designed for use in harsh environments, and both products’ digital input channels have 3500VDC isolation protection, wide input range from 5V to 30V and wet or dry contact setting through DIP switch selection. For their relay output channels, they have 1500VDC isolation protection, Form C relay and 30VDC at 1A or 120VDC at 0.5A contact rating. LED indicators show the status of all I/O channels and both products are DIN-Rail mounting.
