SL-83 – two channel T&A and access controller

SL-83 (2)Two channel time & attendance and access controller using iButtons, RF tags or magnetic cards.


  • alphanumeric LCD 24×2 with backlighting
  • 2 configurable reader inputs (iButton, RF, PIN keyboards etc.)
  • 2 voltage-free sensor inputs
  • 2 voltage-free egress inputs
  • 2 configurable relay outputs (12V or voltage-free, both polarities)
  • outputs are galvanically isolated from MCU in all 4 configurations
  • configurable relay-on time for all 2 relays
  • time & attendance function (buffer for 8192 clockings)
  • access control function (ID table of 4096, time and input state discrimination possible)
  • PLC-type configuration (all events can affect all outputs)
  • random event generation for all readers with settable probability (e.g. spot searches for exits, breath tests for entries)
  • 8 time-events for signal generation on relay outputs (e.g. start/end of shift and coffee break signalling)
  • Forced Entry alarms (door opened, corresponding relay inactive)
  • Door Open Too Long alarm (time limit settable)
  • AUX channel for attaching up to 8 additional AUX devices (readers, terminals, large clock displays etc.)
  • PC communication over active 4-wire current loop (to 1000m)
  • RJ-45 connector for direct connection to Ethernet – TCP/IP
  • 12V/7Ah lead battery for up to 24h autonomy
  • battery charger with up to 2,5A
  • battery deep-discharge protection
  • alarm output for indicating no-AC input voltage condition
  • most connectors available both as RJ-11 and detachable screw terminals (5mm pitch)
