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

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
