Omron H3BA-N8H-110VAC Timer

The Omron H3BA-N8H-110VAC is a high-performance multi-range solid-state timer designed for precise sequence control in industrial HVACR and automation panels. Operating on a 110VAC input voltage, this 8-pin terminal timer features a versatile output configuration including an SPDT time-limit contact and a switchable instantaneous SPDT output. Engineered for DIN rail mounting or surface installation via appropriate sockets, the H3BA-N8H allows for field-adjustable timing scales ranging from 0.05 seconds to 300 hours. The analog dial interface provides technicians with tactile reliability and at-a-glance status verification. This industrial plug-in timer is optimized for high-cycle applications where timing repeatability and noise immunity are critical. Its compact 1/16 DIN housing ensures compatibility with standard control cabinet footprints, making it a reliable drop-in replacement for aging electro-mechanical timing relays in logic-controlled cooling and heating systems.

• Dual Output Versatility: Offers both time-delayed and instantaneous contact modes to simplify complex control wiring.
• Wide Timing Range: Multiple selectable time scales eliminate the need to stock multiple fixed-range SKUs.
• Industry Standard Form Factor: Seamlessly integrates with 8-pin round sockets for fast field swaps and reduced downtime.
• High Repeat Accuracy: Ensures consistent performance in critical 110V control circuits with minimal drift.

How do I switch the output from time-limit to instantaneous?
The mode selector on the front face allows you to toggle the second contact set between a timed delay and an instantaneous response upon coil energization.

What is the maximum contact rating for this timer?
The internal relays are typically rated for 5A at 250VAC resistive load, making them suitable for pilot duty and small motor starting circuits.

Which socket is required for the H3BA-N8H-110VAC?
This model utilizes a standard 8-pin circular configuration, compatible with P2CF-08 or PF083A sockets.
