These alarms accept DC voltage/current input signals and provide relay output if the input exceeds user-defined set-point limits.

361A: DC-powered
461A: AC-powered

Numerous options and features make these alarms easy to use and well-suited for a wide range of limit monitoring and on/off controller applications. Three-way isolation eliminates ground loops to simplify installation. And for easier use in the field, these alarms withstand extreme temperatures and have accessible set-point voltage test points. Other features include alarm/power status LEDs and independent set-point and dead band adjustment pots.

  • 100% adjustable set-point via 15-turn pot handles more applications and provides better resolution
  • 100% adjustable dead band via 15-turn pot prevents false trips and eliminates alarm chatter
  • Set-point test points are accessible on front of unit for quick verification with digital voltmeter probe
  • Dual relays offer the flexibility of high/low, high/high, or low/low alarm set-point operation
  • Three-way isolation eliminates ground loops
  • Jumper-selectable DC voltage or current input reduces inventory stock
  • Jumper-selectable fail-safe operation enables alarm actuation on power loss in critical applications
  • Wide power supply range (361A) handles more applications to reduce inventory stock
  • DC power units (361A only) carry lower voltages and do not require expensive conduit for safer and easier installation
  • Diode-coupled power (361A only) supports the use of redundant power supplies for critical applications
  • Excellent accuracy, stability and no loose internal wiring ensure reliable alarm trips
  • Operating temperature range: -13°F to 167°F (-25°C to 75°C)
  • DIN rail G or T mount
  • No certification/approval required
