DIN rail bistable relay FF BIS-413I with time switch on/off 230V 16A InRush 160A/20ms 1P screw terminals 1 module

The DIN rail bistable relay FF BIS-413I with integrated time switch is a compact 1-module device designed for installation in distribution panels and control cabinets. It provides a latching (on/off) single-pole contact for switching 230 V AC circuits and includes a programmable time function to control delayed on or off operations. The relay supports continuous switching currents up to 16 A and is rated to tolerate short-term inrush currents up to 160 A for 20 ms, making it suitable for loads with high startup currents such as certain lamps or motors. Screw terminals and a standard DIN-rail housing enable straightforward mounting and wiring in building automation and lighting control systems.

Advantages

The bistable construction preserves the relay state after coil de-energization, reducing power consumption during idle periods. The integrated time switch allows timed control without extra modules, combining relay and timer functions in a single 1-module device. High inrush current resistance ensures reliable switching of inductive or capacitive loads at startup. Screw terminal connections and a compact footprint simplify installation in multi-device panels and minimize space use.

Suitable for

• Lighting control in residential and commercial distribution boards
• Building automation for timed switching of circuits
• Energy-saving applications where devices must remain in a set state after a power interruption
• Switching loads with high inrush currents such as LED drivers, fluorescent ballasts, or small motors

Key specifications

• Rated control voltage: 230 V AC
• Contact configuration: single-pole (1P) bistable (latching)
• Continuous switching current: 16 A
• Inrush current tolerance: 160 A for 20 ms
• Mounting: DIN-rail (1-module housing)
• Connection type: screw terminals

How to use

Mount the relay on a standard DIN-rail inside a distribution panel and make electrical connections using the screw terminals according to the wiring diagram supplied with the product. Use the control input to change the relay state; the device will latch in the last commanded position when the control signal is removed. Configure the integrated time switch for delayed on or off functions following the manufacturer's instructions so that timing behavior matches the intended application. Verify load ratings and ensure the connected circuits do not exceed the 16 A continuous rating; consider the inrush tolerance when connecting lamps or motorized loads.

Usage recommendations

For reliable operation, install the relay in a ventilated panel environment and avoid exposure to excessive dust or moisture. Use conductors and connectors sized for the 16 A load and follow local electrical codes. When controlling loads with significant inrush currents, confirm that cumulative inrush from multiple devices does not exceed the distribution circuit capacity.
