  • Trends in circuit protection
    solidstate remote power controller from E-T-A is typical of smart power relays that combine an electronic power relay, an overcurrentprotection-device, and a status indicator into a single unit. Engineers have long considered circuit protection a stable if somewhat unglamorous area. However, that stability
  • Tiny micros open new frontiers
    traditional 555 timers, pulse-width modulators (PWMs), remote-control encoders, pulse generation, programmable frequency source, and resistor-programmable oscillators. Another area is mechatronics, the melding of traditional mechanical functions like switches, knobs, relays, timers, and electromechanical
  • Safety rides the bus Packaging system demonstrates AS-I-Safe
    systems often have a PLC with rack I/O that lets a computer monitor and control each machine function. However, since the advent of networks such as Profibus, AS-I, ModBus, DeviceNet, and Remote I/O, distributed I/O architecture has been widely adopted for machine control. It replaces the large
  • SP Solutions IVR/RADIUS Services for Calling Card, Prepaid and Other Payment Systems
    to be properly authenticated, authorized and credited/debited to caller accounts. Voice prompts can also be cached locally on the Tenor Switch for improved application performance. RADIUS: The RADIUS (Remote Authentication Dial-In User Service) protocol is an industry standard that is widely used by billing
