Encoder
The HOG 16 hollow-shaft incremental encoder uses double scanning of incremental disk by two separate electronic systems mechanically displaced by 180°. HTL-signals are electrically isolated and available for the control of two frequency converters or as a double safety system. The device is mounted on two 2,600-kW tandem drives on board a suction dredger.

Delay line
A five-tap, solid-state delay line for 3V applications supplies total delays from 20 to 300 ns and tap-to-tap delays from 4 to 60 ns. The element comes in 8-pin DIPs and surface mount packages to save on pcb area. It is designed to reproduce both leading and trailing edges with equal precision. Each tap is capable of driving up to ten 74LS loads. Delays are specified over both commercial and industrial temperature ranges.

Battery servicing
The CASP/2500 services emergency battery packs, often used to power emergency lighting on aircraft feature several automatic functions such as charging, discharging, capacity verification, and recharging. The system can recognize most common types of batteries and can be programmed to receive those types of batteries it cannot readily identify. The CASP/2500 can also assist when commissioning new battery packs placed into service for the first time.

Digital signal controller
The 16-bit dsPIC digital signal controller combines the control advantages of a microcontroller with the high computation speed of a digital signal processor (DSP) to produce a single-chip solution for embedded systems designs. It provides DSP functionality in the familiar PICmicro microcontroller Integrated Design Environment, simplifying implementation by engineers familiar with microcontrollers.
