WAGO: Compact triggered timer relay

Triggered Timer Relay supports E-stop circuitry within space-restricted panels.
FILED IN:  Controls  > Machine components  > Relays

Upon E-Stop activation, the falling edge of a trigger signal initiates the 859-477’s off-delay timer for sequential shutdown. The device’s four highly adjustable time delay ranges enable a PLC to log the stopped position of all components. This helps provide smooth and efficient restart of intricate machinery, such as that found in material handling and packaging.

A customer-driven design, WAGO Engineering Services focused on usability by developing the 859-477 with a high-resolution, top-mount potentiometer. The 12-turn potentiometer augments two side-mount DIP switches that select time ranges of: 0.5s–2s, 1.0s–12.0s, 5.0s–90s and 50s–12 minutes. The unique top-mount potentiometer enables users to fine-tune time delay settings without removing 859-477 from DIN-rail.

The Triggered Timer Relay utilizes WAGO’s industry-proven, 6mm-wide relay housing, making it one of the market’s most compact. A top-mount LED indicates switching status of the electromechanical single-pole, single-throw Normally Open relay output. 859-477 features an operating temperature range of 0°C to +40°C and 6 A max contacts. Vibration-resistant, maintenance-free CAGE CLAMP® Spring Pressure Technology ensures long-term signal integrity.
