Narrow timer relays have labeled thumb wheel to set time
Phoenix Contact’s range of narrow single-function timer relays, the ETD-BL, is designed to save valuable cabinet space. They measure just 6.2 mm, up to 70% narrower than conventional timer relays.
The relays have a labeled thumb wheel at the front to ensure precise time settings. To protect against unintentional adjustments, the wheel is recessed into the casing and can be adjusted using a screwdriver. Time settings range from 0.1 to 5 seconds and have four functions for easy customization.
The 24 V dc timer relays transmit output signals by using a floating change-over contact. Equivalent potentials can be quickly connected using a plug-in bridge system from Phoenix Contact’s PLC relay product range. An optional PLC-V8 adapter can connect the relays to Varioface system cables quickly and securely.
The new compact timer relays can eliminate the need for mini controllers in some applications. They require no software programming, saving both time and money. Only one selection of time parameter is all that is needed.
