WE LOOKED AT EVERY DETAIL 
IN THE DESIGN OF EZ I/O
Snap-in I/O Module
EZI/O modules are designed with one thing in mind – 
modularity! Each and every EZI/O module can be utilized with 
EZPLC, EZ Series TouchPLC and EZ series TextPLC for a truly 
modular I/O.
Removable Terminal Block
EZI/O modules come with male headers to accommodate 
11 point removable Phoenix terminal blocks (UL rated for 300V 
10 Amp 14 AWG) for ease of wiring.
Thermocouple Input Module
4 differential inputs, Types J, K, S, T  
±0.1° C or F resolution, ±15 ppm 
per deg. accuracy
RTD Module
4 channel RTD inputs, Types Pt100, Pt1000, 
120 Ni, 10 Cu, No User Power Required, 
12 Bit resolution
4 Analog In, 4 Analog Out Current
Single ended, 0 to 20 mA or 4 to 20 mA DIP 
switch selectable, 12 Bit resolution
4 Analog In, 4 Analog Out Voltage
Single ended, 0 to 5 Vdc or 0 to 10 Vdc DIP 
switch selectable, 12 Bit resolution
8 Analog In Current
Single ended, 0 to 20 mA or 4 to 20 mA DIP 
switch selectable, 12 Bit resolution
8 Analog Input Voltage
Single ended, 0 to 5 Vdc or 0 to 10 Vdc DIP 
switch selectable, 12 Bit resolution

100 KHz counter with 4 outputs each
WIDE VARIETY OF AC/DC, IN/OUT, DIGITAL/ANALOG, 
THERMOCOUPLE, RTD & COUNTER I/O MODULES
I/O Status LED Indicators
LED indicator lights on every channel to 
help troubleshoot and debug field wiring.
No Power Budgeting
All EZ Family PLCs are designed to handle 
any combination of EZI/O modules without 
any need for external power supplies. EZI/O 
modules consume only 20 to 40 mA power 
at 3.3V. 
Compact
Extremely small size, 
51 x 51 x 25 mm (2 x 2 x 1").
Mix-n-Match
AC and DC, input and outputs are 
mixed-n-matched to provide 
maximum flexibility.
Wiring Duct for Routing Field Wires
Every EZI/O module has a wiring duct for routing field wiring in 
neat bundles.
