16-channel Relay PCLD-788 Multiplexer Board 1 IPPC & AWS Features Features § 16 to 1 channel expansion 2 § Differential and fully isolated multiplexing TPC § Break-before-make relay control § “Channel closed” signal for precise A/D triggering 3 § Up to 16 PCLD-788s can be cascaded for 256 channels FPM § Easy wiring for large channel count configuration § Onboard cold-junction circuitry for thermocouple measurement 4 ATM 5 DA&C 6 cPCI 7 Introduction ADAM-3000 The PCLD-788 multiplexes 16 channels into a single I/O channel of an A/D converter, voltmeter or IEEE-488-based instrument. Up to 16 PCLD-788s can be cascaded for a total of 256 fully-isolated differential channels. The PCLD-788 can be controlled by any PC-LabCard via a 16-bit 20-pin digital output port, found on cards such as the PCL-711B, PCL- 8 812PG or the PCL-818 series. eConnectivity Channel selection (0-15) and board selection (0-15) are done by programming the high-order four bits and low order four bits of a digital output byte from the main I/O card in use. 9 ICOM Specifications § Input Channels 16 isolated differential inputs 10 § Programming D/O bit 0, 1, 2 and 3 for channel selection, D/O bit 4, 5, Software 6 and 7 for board selection.

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.
