32-ch Solid-State Relay (SSR) Board,
Ethernet IP Controlled
IA Series-3000 Daisy-Chain
Introduction
The IA-3121-E is an Industrial 32-ch Solid-State Relay module, Ethernet IP Controlled, with an
RS-232 expansion port, allowing non-IP controllers to be chained and controlled while sharing
the same IA-3121-E IP Address.
The Solid-State Relays are capable of handling DC Powered Loads in a Voltage range of 12 to
30VDC, Sinking a current of up to 1Amp per channel. AC Load is NOT supported.
The main advantage of Solid-State Relays is incomparable Long Operation Life, Fast Respond,
Silent Operation and best fitting Inductive Loads.
The IA-3121-E may be referred to as a High Power 32-ch Digital Output Module, with an Open-
Drain Output Stage and an output current capability of up to 1Amp on each channel.
It has a small footprint, 136x147mm, and it may be easily DIN-Rail Mounted. Screw mounting
kind is possible as well.
Features
32-ch DC Solid-State Relays
1Amp @12-30VDC, 2Amp Pulse
TCP/IP or UDP Controlled
DHCP or Static Address Operation
Built-in Web Page for a simple Set-up
RS-232 Expansion Port
Small Footprint
DIN-Rail Mounting ready

Command Set
The following table is a quick reference table for the IA-3121-E , A host computer / PLC may
control the IA-3121-E by simply sending ASCII commands though a standard COM port. Each
command is structured from a delimiter character, modules address, command character, data
if any carriage returns character. All commands must use UPPER CASE characters.
