Introduction

The dS2832 is an Ethernet connected relay module featuring 32 channels of 16Amp 250Vac re-

lays. Each relay has both normally open (NO) and normally closed (NC) as well as the common

available on three terminals.

In addition to the relays, the dS2832 has 8 flexible I/O channels which may be individually

configured to be:

1. NPN transistor output.

2. Active low input with pull-up (allows direct connection of volt free contacts).

3. Active low input without pull ups (easy to connect logic level inputs).

4. Analogue 12-bit inputs using a 4.096v reference (0v-4.096v input range).

5. Analogue 12-bit inputs using a 5v reference (0v-5v input range).

The dS2832 requires a 12v 2Amp power supply such as this one:

The dS2832 has four built in control methods.

Primary control method is graphically by using its built in secure website.

Secondary control may be one of:

ASCII - type in commands via a program such as PuTTY.

Binary - Command set using binary codes

Modbus – Functions 1, 4, 5 and 15 supported

And if you should wish to modify the supplied firmware – you can.

Behind the scenes there is dScript, a powerful multi-threaded operating system and program-

ming language. The supplied firmware is written in dScript as well as HTML, CSS and

Javascript on the webpages and the full source is in the separately down-loadable dScript sup-

port package.

You do not need to use dScript at all, but its great to know its there - just in case you do.
