ELECTROMATIC S-SYSTEM SB 105 724 INTERVAL ON OPERATE RELAY WITH BASE 0.8-18 SEC

What is the SB 105 724 Interval Relay?

The Electromatic SB 105 724 is an interval on-operate solid-state relay, intended for delay timing control. On application of power, the relay waits until the specified interval (0.8 to 18 seconds) before switching on. This delay-on functionality makes it highly suitable for procedures with controlled start-up timing or sequential operation.

Important Features

Brand: Electromatic

Model: S-System SB 105 724

Function: Interval On Operate

Time Range: 0.8 to 18 seconds (adjustable)

Relay Type: Solid-state

Socket/Base: Included

Mounting: Plug-in with standard base

Voltage: Generally compatible with 24V to 240V AC/DC (check according to precise variant)

How It Works

When power is applied to the relay, the timing circuit within begins counting. After the specified time has passed, the relay output is switched on. It is not like an “on-delay” type where the output is kept energized for the duration. On this interval on operate model, the delay occurs prior to the output being energized, enabling time-controlled triggering of the circuits.

Applications

The SB 105 724 is typically used in:

• Industrial automation systems
• Motor start sequencing
• Conveyor belt operations
• HVAC systems
• Packaging machinery
• Safety and shutdown delay systems

Its accurate timing function aids in automating processes, decreasing mechanical component wear, and enhancing operational safety.

Why Use the SB 105 724?

Here’s why this relay stands out:

✅ Durable solid-state design – Less moving parts translate to longer lifespan and less maintenance.

✅ Broad timing range – The adjustable 0.8–18 sec range accommodates different timing requirements.

✅ Durable and compact – Perfect for limited space control panels.

✅ Simple installation – Due to plug-in base as well as traditional pin arrangement.
