SR560 alarm unit - Inor

SR560 alarm unit - Inor

Dual Channel Alarm Unit for mA/V Signals

SR560 is designed for monitoring mA or V signals in the process industry.
The two channels are fully independent.
The SR560 is specially designed for reliable safety triggering without false alarms.

High configuration flexibility allows for adaptation to required alarm functions.

  • Two fully independent isolated channels
  • Current and voltage input
  • Reliable and interference free safety alarm without false alarms
  • High configuration flexibility with solder jumpers
  • Adjustable time delay, hysteresis and relay functions
  • Available for AC or DC power supply
  • DIN-rail mounting
  • Plug-in screw terminals
