Application Scenarios Industrial automation control cabinet, mechanical equipment, building automatic control system. Used for time‑delay interlock, sequential action control and timing signal triggering.
Performance Parameters High timing accuracy under wide power supply fluctuation. Stable relay contact switching performance. Flexible function setting adapts to different field timing requirements.
Material Composition Flame‑retardant plastic housing. Internal timing logic circuit board, relay contact assembly. DIN‑rail snap‑in spring clip. Screw‑type wiring terminals.
Structural Characteristics Compact DIN‑rail modular housing. Front panel equipped with function DIP switches, timing adjustment potentiometer and status LED indicators. Input power and output contact wiring terminals locate at bottom. Built‑in spring clip for DIN‑rail mounting. Weight approximately 0.15 kilogram.
Working Principle After auxiliary power is applied, internal timing circuit completes initialization. When trigger condition is satisfied, timing circuit starts to count according to preset parameters. After preset time elapses, internal relay contact acts to complete switching of external control loop. LED synchronously indicates working status.
Installation Requirements Mount 1SVR040000R1700 onto standard DIN rail. Complete power supply and control loop wiring. Set timing mode and timing range via DIP‑switch and potentiometer.
Usage Notes Do not exceed rated contact switching voltage and current. Adjust timing parameters according to field process requirement. Keep good cabinet ventilation environment. Check terminal tightening torque during regular maintenance.
