General Certifications CE Connectors Controller: 2 x 20-pin box header, second connector in parallel for daisy chaining I/O: Screw terminals Dimensions (L x W) 205 x 114 mm (8" x 4.5") Mounting 4 x screw holes for flat surface mounting Power Consumption +5 V @ 380 mA max. PCLD-788 Block Diagram 16 to 1 channel expansion Differential and fully isolated multiplexing Break-before-make relay control “Channel closed” signal for precise A/D triggering Up to 16 PCLD-788s can be cascaded for 256 channels Easy wiring for large channel count configuration Onboard cold-junction circuitry for thermocouple measurement Pin Assignments Introduction 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™ product via a 16-bit 20-pin digital output port, found on cards such as the PCL-711B, PCL-812PG or the PCL-818 series. 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.
