PRODUCT INFORMATION
Models: I-7044, I-7044D
Isolated Digital Input/Output Module
with LED Display
(I-7044D)
I-7000 is a family of network data acquisition and control modules providing analog to digital, digital to
analog, digital input/output, timer/counter and other functions. The modules can be remotely controlled by a
set of commands.
The digital input/output modules support TTL signal, photo-isolated digital input, relay contact output, solid-
state relay output, PhotoMOS output and open-collector output.
The I-7044 is a 4-channel digital input and 8-channel output module. The 4 inputs are isolated with common
power, and outputs are isolated with common source. Isolation voltage up to 3750Vrms protects damage
from suddenly industrial electric power shock. The digital input channels can monitor active TTL signals, and
sense passive switch on/off signal. The output channels are open-collector transistor switches that can be
controlled from a host PC or you can use the switches to control solid-state relays.
The I-7044D is the I-7044 with LED display.
