Description

The Time Mark Model 409 is a compact, socket-mount device for level control of conductive liquids. The internal relay is energized when operating power is applied. When the liquid level reaches the probe, the relay de-energizes. When the level drops below the probe, the relay will reset.

A fixed, two-second time delay prevents oscillation due to wave action. Probe cables may be shielded or un-shielded. If the liquid container is made of a non-conductive material, a common electrode is required. Other features include an LED indicator to show the output relay status and an adjustable sensitivity setting. The Model 409 requires a standard 8-pin octal socket (sold separately).

Features:

• 409-230VAC = 200-250VAC Operating Voltage
• Automatic control of liquid level
• Solid-state sensing circuit
• Adjustable sensitivity
