• Low: 0-1 VDC
• High: 9-24 VDC
Relay Output (Digital Output)

The relay output must be supplied from an isolating transformer using a secondary listed fuse rated at
maximum 3.3A DC and minimum 30V DC.
Analog Inputs (AI)
Netbiter EasyConnect EC220 provides 2 analog inputs. Each input can be configured for one of the
following functions:
• PT100: PT100 temperature sensor (range -50° to +150°C). This is the default setting.
• Current: 0-20 mA (Input resistance 270 Ohm)
• Voltage: 0-10 VDC (Input resistance 280 kOhm)
The function of each analog input is selected by its own switch, which is located inside the unit. To ac-
cess the switches, remove the cover of the unit by unscrewing the two top screws, using a T10 torx
screwdriver. Also loosen the two lower screws, to make it easier to open the cover. Lift the cover care-
fully and take care not to damage the antenna cable.
Set the switch to match the desired function for the analog input, as shown in the illustration.
When finished, replace the cover, again taking care not to damage the antenna cable. Re-tighten all
screws.
