Schneider Electric RE17RMMW Time Delay Relay 100hr Spdt

Product Description

The SCHNEIDER ELECTRIC RE17RMMW is a multi-function time delay relay designed for control panel and industrial automation applications. It supports nine selectable timer functions and covers a wide supply voltage range of 12 to 240 volts AC or DC, making it adaptable to a broad range of control circuit configurations. The relay features a single-pole double-throw (SPDT) output contact rated at 8 amps. Timing range spans from 0.1 seconds up to 100 hours, with the active range selected via a built-in selector switch. Licensed electricians and controls technicians are the primary installers.

The RE17RMMW is suited for residential, commercial, and light industrial control systems where programmable timing sequences are required. Typical applications include HVAC fan delay circuits, pump sequencing, motor start delay, and lighting control panels. Its asymmetrical, interval, pulse, and power-on or power-off delay modes give installers flexibility to match the relay to the specific control logic required without substituting additional components.

Key Features

• Nine timer functions: Asymmetrical, Delay On Break, Delay On Make, Interval, Power Off Delay, Power On Delay, Pulse Delay, Pulse-on, and Symmetrical
• Wide supply voltage range: 12 to 240 volts AC or DC — single unit covers most control circuit voltages
• Timing range from 0.1 seconds to 100 hours across multiple selectable ranges
• SPDT output contact rated at 8 amps for direct load switching
• Selector switch adjustment — no external programming tool required

Compatibility

Designed as an OEM-style replacement or new-installation time delay relay for control panels requiring a multi-function, wide-voltage SPDT timing relay.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements and local codes. De-energize the control panel and verify zero voltage with a meter before wiring. The wide AC or DC voltage range eliminates the need to match a specific transformer secondary, but verify the load current does not exceed the 8-amp contact rating. Secure all wiring terminations and confirm the selector switch is set to the correct timer function and range before restoring power.
