The dS2832 is an Ethernet connected relay module featuring 32 channels of 16Amp 250Vac relays. Each relay has both normally open (NO) and normally closed (NC) as well as the common available on three terminals. 8 flexible I/O channels with a choice of VFC, NPN, or 12-bit analog input.
Devantech 8 channel, 16A Ethernet relay board allows simple relay automation or create Peer-to-Peer control in just a few clicks with powerful dScript programming language. Communications are USB for development, RJ45 for normal access.
Hardware
Serial ports - 1 x TTL level serial port, 1 x RS485 port.
Relays - 32 with up to 16Amp @24vdc or 250vac, screw Terminals for N/O N/C and Common contacts
I/O - 8 flexible channels, your choice of VFC input, NPN output or 12-bit analogue input.
Communication - USB for development, RJ45 Ethernet for normal access
Power - 12V DC jack 2.1mm (adaptor sold separately)
The dS2832 provides 32 volt free contact relay outputs with a current rating of up to 16Amp each, 8 flexible I/O's which can be analogue or digital and 1 serial port (3.3v level). The module is powered from a 12vdc supply which can be regulated or unregulated. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
LED indication
The dS2832 provides a red LED mounted immediately next to each relay to indicate whether it is in a powered state (LED on), there are also two LED's mounted in the Ethernet connector which will flash with Ethernet traffic. A row of three LEDs, Blue, Green and Red, are available for status indication. The Red LED lights when the module is in bootloader mode – this is when the IDE is uploading system firmware to the module. The Green LED lights the board begins running user programs. All three LEDs are available and can be controlled as digitalports 33-35.
The “FlashingLeds” example provides a colourful display showing how to use them.
There are also LEDs on the I/O lines. These indicate the I/O status in digital output and VFC input modes only.
Power supply
The dS2832 requires a 12v DC supply capable of supplying a minimum of 2A. This is most easily provided by a low cost mains adapter. A suitable universal adapter is available on our website and may be ordered along with the modules. Connection is via the 2.1mm DC jack socket. Positive on the center pin.
Operating temperature
-40C to +70C
Power relays
Four 16A volt free contact relays are provided for switching a common input between a normally closed output and a normally open output. The relay coil is powered by the 12vdc incoming supply on user command.
Connection examples
Example input - connecting a switch
Connecting a simple switch could not be easier, just wire the switch between a pin (P) and ground (0v). When the switch closes the input will become active. Make sure you use the 1 option in the digitalport declaration to enable the ports passive pull-up
Example output - connect a relay
You can connect your own 12V relays, the first coil pin of the relay is wired to the 12V supply terminals on the board, the other is wired to the output pin (P). When the output pin becomes active it is driven down to 0V ground, the relay will have 12V across the terminals and switch, so COM is connected to NO (Normally Open).
