1.6 Hardware Installation
This chapter describes how to install and configure the hardware
1.6.1 Mount the Unit
The
IOT400 series products can be placed on a desktop, or use extender to place on DIN-Rail bracket or mount
on the wall.
1.6.2 Connecting I/O Devices
The IOT400-DL101
provides a 10-pin terminal block for one serial console port, one digital input (DI), one
digital output (DO), one analog input (AI), and DC Power (DC5~12V) ports. Connect the field device(s) to the
I/O ports with the right pin assignments as shown below.

(Depends on external device)
If the AI signal range of your device will run out off the design spec. of Data Logger (0-10V), you have to add a
certain scaling circuit to prevent overflow readings and even damage the Data Logger.
