The 260A accepts a 4 to 20mA input signal and provides a dry contact relay output if the input exceeds a user-defined set-point limit. Power is received from the input loop.

These alarm relays are ideal for local fail-safe alarming with existing process transmitters. They are easily installed on a process loop because they do not require an additional power supply and feature a very low voltage burden. A long list of features allows the 260A to adapt to most applications.

  • Excellent accuracy and stability ensure reliable measurements in harsh industrial environments
  • RFI and EMI resistance minimize the effects of environmental noise
  • Loop-power design and low 4.5V DC voltage drop enable easy installation
  • Hi/lo fail-safe option trips alarms above or below set-point
  • Automatic or manual reset option permits latching alarms
  • Adjustable set-point (4 to 24mA) handles more applications
  • LED gives visual indication of alarm status
  • Six dead band levels (DIP switch select) offer further flexibility
  • 50mS response time delivers fast alarm notification
  • Compact, 1-inch wide housing uses less space for easier installation
  • Operating temperature range: -13 to 167°F (-25 to 75°C)
  • DIN rail G or T mount
  • No certification/approval required
