Timer relayWAGO Corporation’s triggered timer relay supports e-stop circuitry within space-restricted panels. 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 adjustable time delay ranges enable a PLC to log the stopped position of all components. This helps smoothly and efficiently restart intricate machinery, such as that found in material handling and packaging. The 859-477 is developed 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 top-mount potentiometer lets users fine-tune time delay settings without removing 859-477 from the DIN-rail. The triggered timer relay uses 6mm-wide relay housing. A top-mount LED indicates the switching status of the output. It has an operating temperature range of 0°C to +40°C and 6 A max contacts.
