Understanding the H3Y-2-C Solid-State Timer Relay
The Omron H3Y-2-C is a versatile timer relay designed for simplicity and efficiency. As a solid-state timer, it utilizes semiconductor components for switching, offering advantages over traditional electromagnetic power relay types in terms of lifespan and switching speed, especially in high-frequency applications. Its core function is power on-delay, meaning the timing period begins as soon as power is applied to the coil terminals.
Once the preset time elapses, the internal relay contacts change state. This reliable mechanism is fundamental in countless industrial automation sequences, from motor start delays to process timing. The H3Y-2-C model stands out for its straightforward operation and compact footprint, making integration into control panels seamless.
Key Features of the 8-Pin Plug-in Design
One of the most user-friendly aspects of the H3Y-2-C timer is its standard 8-pin plug-in terminal base (compatible with sockets like PYF08A). This design drastically simplifies installation and maintenance. Instead of hardwiring directly to the relay, you wire to the socket. If the timer needs replacement or testing, you simply unplug it from the socket.
This plug-in terminal configuration is standard across many control components, promoting modularity in panel design. The 8-pin layout provides connections for the supply voltage (AC or DC) and the DPDT output contacts. An LED indicator clearly shows the operational status (power ON and output energized), aiding in quick diagnostics. This simplicity ensures even technicians less familiar with intricate electrical systems can manage replacements easily.
Configuring Time Delay with the H3Y-2-C
Setting the desired time delay on the Omron H3Y-2-C is remarkably intuitive. The front face features a clear dial marked with time units and a multiplier range. Users simply rotate the dial to select the precise delay required for their application, ranging typically from fractions of a second up to several hours, depending on the specific model variant purchased.
This analog adjustment allows for quick changes without needing programming software or complex interfaces, which is ideal for many machine control scenarios. The accuracy and repeatability of the time setting ensure your processes run consistently cycle after cycle. Precise timing is crucial, whether coordinating conveyors, controlling lighting, or managing heating element cycles.
DPDT Output for Versatile Control
The H3Y-2-C features a Double Pole Double Throw (DPDT) output contact configuration. This essentially provides two separate electrically isolated switches within the single relay, each with a normally open (NO) and normally closed (NC) contact. This DPDT 2NO 2NC arrangement offers significant flexibility in circuit design.
You can use one set of contacts to switch a load ON after the time delay, while simultaneously using the second set to switch another load OFF, or perhaps signal the status to a control system like an HMI. This versatility allows the H3Y-2-C timer to handle more complex control tasks compared to simpler SPDT (Single Pole Double Throw) relays. Its output contacts are typically rated for loads up to 5A, suitable for controlling contactors, small motors, lamps, and other common industrial loads.

Frequently Asked Questions
The H3Y-2-C uses a standard 8-pin octal-style base. Compatible sockets include the Omron PYF08A (surface/DIN rail mount) or the PTF08A (back connecting) models.
No. You must use the correct voltage type (AC or DC) and rating specified on the timer relay label. Applying the wrong voltage type or level will damage the product. Ensure you order the DC24V model for 24 VDC systems and the AC220V model for 220 VAC systems.
DPDT stands for Double Pole Double Throw. It means the relay has two independent sets of changeover contacts. Each set has a common terminal, a normally open (NO) terminal, and a normally closed (NC) terminal, providing great flexibility for controlling multiple circuits or functions simultaneously.
Omron specifies typical setting accuracy, repeat accuracy, and influence of voltage or temperature variations in the product datasheet. Generally, these timers offer good accuracy suitable for most industrial timing applications, often within ±0.5% to ±2% of the full scale, but always consult the datasheet for precise figures for your specific model and operating conditions.
