61F-GPN-BT/-BC

Features

Compact plug-in (11-pin) level controller (DC supply)

This controller is for single- or two-point level control. 24VDC supply allows for usage in locations without AC power supply. Relay contact chattering usually caused by waves has been eliminated by using open collector output, reducing contact wear.

  • Adjustable sensitivity: operation range: 0-100kΩ
  • Red LED for operation indicator
  • Conforms to EMC and LVD directives
  • UL/CSA approved
  • Probes need to be ordered separately
