A new Industrial Relay Controller with 16-ch relays, 16 isolated Digital
Inputs and two watchdog protection manufactured by Intelligent-Appliance.
Online-Devices announced a new 16 Relays/16 Isolated Digital Inputs, Industrial Relay
Controller, the IA-3116-U2i, with two Watchdog protection circuits Manufactured
by Intelligent-Appliance. The original circuit keeps the on board CPU from
harsh hostile environment while the second one watches the communication and
host computer secure operation.
This updated solution handles "Dry-Contact", Industrial Negative Logic as
well as Positive Level signals without any Jumper or software setting.
The new relay controller includes an Isolated USB Port, to keep the host computer
from the Factory Floor or any other hostile environment. Additional COM Port
supports a transparent, buffered, Multi-Drop operation, with a board expansion
capability of up to 255 units.
The relays provided on this board have a current rating of 2 Amp at 30VDC, and 1 Amp at 125VAC, while contact version includes both SPST and SPDT, Form A and Form C.
An optional board version, the IA-3116S-U2i, includes additional Voltage Suppressors for handling Inductive Loads. These suppressors limit the relay contact operation range to 39VDC and 30VAC, while
the standard unit, the IA-3116-U2i, supports a voltage range of up to 250VAC.
The Board, released just last month, has already been integrated in a large scale
Automated Parking Machines for I/O Control in Europe. Another project is the
integration of the units on a manufacturing floor of a chocolate and candy
The IA-3116-U2i Commands List includes local and global commands, for handling the boars features in a direct and immediate manner, or to handle several boards synchronized function. Among the
commands list one can find a unique board ID data acquiring command that can
help keeping customer's software privileges, relays emergency state definition
command and more.
The free software support package includes Setup and Operation utility, Software
Drivers and Open Code software examples in VB.5, VB.net, C# and C++ for fast
