Wiring Self Powered Discrete Inputs
⚙
ᐳ
In order to create self-powered discrete inputs with plastic housing variant:
1. ▷
Connect battery negative (B-) to ground and PE (terminal 61).
2. ▷
Fig. 250:
Wiring self-powered discrete inputs
Connect DI common (terminal 66) to power supply 12/24 V (terminal 63, minimum wire
size 0.5 mm² (20 AWG)).
▶
This enables to energize the discrete inputs against ground.
The Protective Earth terminal 61 is not connected on the sheet metal housing.
• Use the protective earth (PE) connector located at the bottom center of the sheet
•
metal housing instead.

Connecting Analog Inputs In Series
The analog inputs of the easYgen-3000XT series are galvanically isolated to the power
supply. This allows for example to share a power setpoint 0/4 to 20 mA with three
devices.
Make sure that the source can drive the resulting burden. (Internal load: AI 1-AI 3 approx.
50 Ω, AI 4 - AI 6 approx. 249 Ω )
