2. Power
To operate this controller is not necessary a permanent connection to a
computer.
This controller can be powered with single or dual power supply for logic.
Usually using one of Con1 or Con2 for power and Con0 only is used for
programming by computer. Con3 is used only for Outputs with Relays.
This is a block diagram of power:
Backup Battery is used only in HID Device mode. The controller can
operate without it, if it is not needed in both modes.

3. Digital Inputs
When the input is not connected, it is assumed level H.
Resistance for input must be less than 1200 Ohm.
4. Analog Inputs
Input can withstand for a short time higher voltages. The only limitation is heat
over the resistance. When an input is set in the current mode, is a normal
resistance of the input slightly to heat up.
With jumper removed, the input is in the Voltage mode, when placed jumper – Current mode.
To select mode:
1. Set Jumper
2. Select MODE from Software
Input X
Rin=91k
Rs h= 500
JpAX
GND
Uses 10-bit ADC. Result is 0 – 1023(0x3FF).
Voltage mode:
The range is 0 – 10.23 V. Step = 0.01V. Rin = 91k.
Current mode:
The range is 0 – 20.46 mA. Step = 0.02mA. Rsh = 500 ohms.
4. Outputs 1- 8
Outputs are implemented with relays SUN RAS-0515, 10A/250V.
5. Outputs 9- 16
Outputs are implemented with optocouplers LTV847. Current through the LED
is 5 mA.
All inputs and outputs are independent.

5. Mode, Software for PC and other features
This controller can operate in two modes: HID Device Mode (jumper
removed) and COM Port Mode (jumper placed). Programming in both
modes is independent. Jumper checked only at power on.
Please see USER GUIDE for PC software / STU2XXXX Assistant / for other
features.
