Digital I/O Board, 32 Isolated I/O Channels, 24V
APCIE-1500
The PCI-Express 32 digital I/O board APCIe-1500 has 32 digital inputs/outputs (24 V or 12 V), 14 inputs are interruptible. The 16 digital power outputs are equipped with protection diodes and filters. The board is fully compatible to the PCI board APCI-1500. It is especially suited for applications like industrial I/O control, signal switching, ON/OFF monitoring of motors, lights etc. in the harsh industrial environment. The APCIe-1500 has interruptible inputs. They supersede continuous cyclical query processes (polling) for routine monitoring and evaluation tasks. This takes load off the processor and the software. At a change of state of the digital inputs the APCIe-1500 generates an interrupt, so that the system reacts on the event through the interrupt routine and herewith fulfils real-time criteria.

Deep Submersible Particle Size Analyzer
LISST-Deep
The LISST-DEEP instrument obtains in-situmeasurements of particle size distribution,optical transmission, and the opticalvolume scattering function (VSF). Using ared 670nm diode laser and a customsilicon detector, small-angle scatteringfrom suspended particles is sensed at 32specific log-spaced angle ranges. Thismeasurement is post-processed to obtainsediment size distribution, volumeconcentration, optical transmission, andVSF. The electronics and opticalconfiguration in the LISST-DEEP are verysimilar to Sequoia’s workhorse, the LISST-100X. However, because of the extremedifficulty associated with keepingalignment under high pressure, the LISSTDEEPhardware design is radically differentfrom the LISST-100X. This allows theLISST-DEEP to be deployed down to 3000m and obtain reliable measurements ofthe in situ particle size distribution andvolume concentration in waters withoptical transmission up to 98.5%.

1000W Ferroresonant Power Supply
Series PRR
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.
