Construction / components

  • For maximum 224 messages: installation 19 "rack system 3x 6U (depth 270mm) for:
    1x power supply card 3U 6M with power outage notification,
    1x CPU 2378, 6U 4M and
    7x input cards FME 32 W, 32 per message, 6U 20M 
    (24V DC / 60V DC / 110V DC / 220V DC labeled with 10 x 32mm light field displays)
  • For maximum 512 messages: installation 19 "rack system 1x 6U (depth 270mm) for:
    1x power supply card 3U 6M with power outage notification,
    1x CPU 2378, 6U 4M and
    16x input cards EK32, 32 per message, 3U 4M 
    (24V DC / 60V DC / 110V DC / 220V DC with LED display)

Interfaces / Ports

  • On the CPU:
    1x USB (for parameterization using an external PC)
    1x RS 485 2x RS 232 (e.g. for printer)
    1x LON FTX
    16x relay outputs change-over max. 125V 0.4A
  • Connection: rear mounted edge-socket connector 32-pin wrap DIN 41612 mounting form D,
    colour-coded connection line 32x 0,25mm²
  • DCF77 radio clock or just optional GPS Clock to synchronize to 1ms

Parameterization

  • via integrated USB interface or remote parameterization by SISSYpro:
    cleartext logging with entering the plaintexts, quiescent / operating current, debounce time on the time scale of milliseconds, switch-on delay and flutter-signal handling on the time scale of seconds
