Latched relay group for flush-mounted installation BIS-412P

Bistable relay for lighting and device control

The BIS-412P bistable relay is an element designed to work in a group system, ideal for hotel, office or multi-family building installations. It allows you to control lighting or other devices from multiple points using buttons connected in parallel. This solution allows users to conveniently control the load from different locations.

Application and functionality

The BIS-412P relay allows you to switch the receiver on and off with each pulse of current from a momentary (bell) button. Central control is also possible – switching all connected receivers on or off simultaneously. The receiver status is indicated by an LED: a flashing LED indicates standby mode (receiver off), and a continuous light indicates on mode.

Installation and compatibility

The relay is designed for mounting on a 35 mm rail and occupies one module (18 mm). It can work with backlit buttons, but attention should be paid to the total current drawn by these buttons (maximum 5 mA). The device operates at 230V AC and has a 1NO/NC contact.

Technical parameters and safety

The BIS-412P relay is characterized by a maximum load current of 16A and the ability to switch loads up to 2000W for incandescent bulbs, 1000VA for fluorescent lamps and 800VA for fluorescent lamps with parallel compensation. It has a protection class of IP20, which means it is intended for indoor use. The power consumption in standby mode is 0.15W, and in operation – 0.6W. The operating temperature is in the range of -25°C to 50°C. It is important to remember that the relay does not have a contact position memory – after a power failure, the contact returns to the off state.
