Eaton ETR4-11-A Multifunction Time Relay, 24-240 V AC/DC, 1 C/O, DIN Rail 031882

The Eaton ETR4-11-A stands out among time relays for its remarkable versatility: seven selectable functions and an ultra-wide supply voltage range of 24–240 V AC/DC in a compact 17.5 mm housing. This single module replaces multiple dedicated timers, simplifying stock and installation in control panels. Whether you need on-delay, off-delay, or flashing operation, the ETR4-11-A delivers reliable timing from 0.05 seconds to 100 hours across seven ranges, all set via a clear rotary switch.

Highlights

• 7 timing functions: on-delay, off-delay, on/off-delay, flashing, pulse shaping, and more
• Wide supply voltage: 24–240 V AC/DC, suitable for global use
• Time range: 0.05 s – 100 h, divided into 7 selectable ranges
• 1 change-over contact (1 C/O) with 5 A AC-1 rating
• DIN rail mounting (EN 60715), only 17.5 mm wide
• LED status indication for quick diagnostics
• Approvals: CE, UL, CSA, CCC, EAC

In daily use

Installation is straightforward: snap the relay onto a standard DIN rail and connect via screw terminals. The rotary switches allow fast setting of function and time range, while the LED confirms operation. With an operating temperature range of -25 to +60 °C and robust electrical life of 100,000 operations, this relay is built for demanding industrial environments. It handles loads up to 5 A at 230 V AC (AC-1) and 3 A at 230 V AC (AC-15), making it suitable for controlling contactors, valves, and small motors.
