Clark Reliance ECID23

  • ECID-23Control Design: Solid state components enclosed in a clear Lexan plug-in style housing. Housing carries no NEMA rating.
  • Contact Design: DPDT (2 form C): two normally open (N.O.) and two normally closed (N.C.), non­powered contacts.
  • Contact Ratings: 5A @ 120, 240 VAC resistive, 1 /10 HIP @ 120,240 VAC. 5A @ 30 VAC.
  • Contact Life: Mechanical - 5 million operations. Electrical - 100,000 operations minimum at rated load.
  • Supply Voltage: 24 or 120 VAC models 10%, minus 15%, 50/60 Hz.
  • Supply Current 120,24 VAC, Relay energized 4.4 VA.
  • Secondary Circuit 12 VAC RMS voltage on probes, 1.5 milli-amp current.
  • Sensitivity: Models operate from 0-100,000 OHM maximum specific resistance. Temperature: -40 to 150° F ambient. Terminals: All connections #6-32 screw type terminals with pressure clamps.
  • Listings: U.L. listed, Industrial Motor Control (508). CSA approved Industrial Control.
LED TERMINAL OUTPUT: Probe in water, + 12VDC, probe out of water, -12VDC.
INSTALLATION:
  1. Install octal socket inappropriate enclosure using two (2) #6 or #8 metal screws.

Direct Mode: Single Level Service: With power applied to the control and the probe on terminal 3 out of the liquid, the load contacts are in their shelf position and a negative 12 VDC signal is present on terminal 4. (LED will not be lit) When the liquid rises to the electrode on terminal 3, the control energizes, changing the state of the load contacts and providing a plus 12VDC signal on terminal 4. (LED will be lit)

Inverse Mode: Single Level Service: With power is applied, with the probe on terminal 3 out of the liquid, the control energizes, changing the state of the load contacts and providing a negative 12VDC signal on terminal 4. (LED will be lit) When the liquid rises to the electrode on terminal 3, the control de-energizes, returning the load contacts to their shelf position and a plus 12VDC signal on terminal 4.
