memo BUS BT2
memo BUS BT2
Digital electronic switch with hourly (daily, weekly, monthly or annual) or astronomical programming, 230 V AC power supply, 2 relays (expandable up to 8), DIN rail installation (3 modules) and with possibility of connecting a GPS module.
What is a time/astronomical switch?
A time/astronomical switch is a device designed for control the switching on and off of electrical circuits according to preset times and environmental conditions such as sunrise and sunset. This device combines the functionality of a traditional time switch with that of an astronomical switch, allowing more precise and flexible control of electricity based on both programmable schedules and daylight conditions. Time/astronomical switches are usually used for automated control of outdoor lighting, such as illuminated signs or garden and park lighting. They can also be used to control irrigation systems.
How it works
The time/astronomical switch works thanks to a timer that allows you to set the desired switching on and off times and thanks to a software inside the device, which allows it to calculate when the sun rises and when it sets. This is possible thanks to programs inside the instrument that allow it to analyze the latitude and longitude at which the device is located, depending on the geographical area set. Memo BUS BT2 offers the possibility of connecting via BUS-485 a GPS module (GEO-1, purchased separately) useful for receiving signals from the satellite system to acquire precise information about the device in which it is integrated, such as time, date, and geographic coordinates (latitude and longitude).
The astronomical twilight switch battery has a life of five years and can be easily replaced when exhausted thanks to the flap on the back of the device.
Why choose Memo BUS BT2
Memo BUS BT2 allows to drive 8 different channels. The first two channels are implemented by the relay of the memo BUS BT2, the other 6 channels are implemented through connection via BUS-485 by RX4-8A and/or RX7-5A remote actuators (purchased separately). Each channel can be associated with a different programming, hourly or astronomical.
Memo BUS BT2 has a built-in Bluetooth interface for using the dedicated “Memo” app, thanks to which you can:
- create programs directly on the smartphone
- transfer the created programs to multiple memo clocks
- acquire programs from one memo and copy them to other memos (copy/paste)
- switch relay outputs manually
- acquire settings (date, time, coordinates) automatically and transfer them to the memo
How the product looks like
The device has the size of 3 DIN. There is a large backlit display on the front of the switch to display the date, time, relay status, and textual guidance.
Keypad lock function
