ADVANTECH PCLD-786
Description
The PCLD-786 is an SSR I/O module carrier board that can accept up to eight photo-coupler isolated solid state relay modules and drive up to eight external relays. It is designed as an accessory board for any PC-LabCard equipped with 16 digital outputs on a standard 20-pin connector. The PCLD-786 accepts up to eight Opto-22 compatible AC or DC SSR (solid state relay) modules in any combination. An AC module always turns its output on at the zero cross voltage point, thus avoiding transient problems caused by heavy inductive loads. DC modules provide fast and bounce-free DC power switching. Compared to mechanical relays, SSRs are more reliable, respond quicker and are more resistant to noise. The PCLD-786 has eight digital output drivers for external relays. Driving voltages are jumper selectable for 5 V, 12 V or external DC power (if overloading a PC power supply is a concern). Each module or driver is equipped with an adjacent red LED for status monitoring.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
