Figure 1: Relay4 additional board
Relay4
The Relay4 additional board is used to connect a development system to high-power consumption devices by using
relays.
Key features:
- Four relays;
- 250V/16A voltage on relay contacts;
- 12V power supply voltage.
How to connect the board?
The Relay4 additional board can be easily connected to a development system via a 2x5 connector CN1. This connector
is connected to a development system port via a at cable with IDC10 connectors. Screw terminals, connected to
working and non-working relay contacts, are used to establish connection between relays supplied on the additional
board and a device. The additional board is supplied with the power supply voltage via a screw terminal CN2.
How to use the board?
The Relay4 board receives a voltage signal from the development system via the CN1 connector. The received signal
is used to activate relays which then turn on a device connected to these relays via screw terminals CN11-CN16.
Connectors W0-W3 are connected to working, whereas connectors NW0-NW3 are connected to non-working relay
contacts.
