2.5.3 Opto-coupled Digital inputs (X8)
The digital inputs accept a digital voltage signal. They read as:
• ON for voltages between 15V and 24V
• OFF for voltages between 0V and 5V
Physical connection specifications:
• Cross sectional Area:
With ferrules: from 0.2 to 2.5 mm²
Without ferrules from 0.2 to4mm²
• Tightening torque 0.4-0.5 Nm
• Stripping length/blade size: 7 mm / 0.6 x 3.5
2.5.4 Analogue Current/Voltage Inputs (X6 and X5)
AI1 and AI2 accept 0-10V or 0-20mA analogue signals according to the terminals selected. Use V+ and GND
for 0-10V signals and I+ and GND for 0-20mA signals. Use of Isolated current/voltage signals is recom-
mended.
Again GND is the common connection and must not be connected to any system earth.
The Analogue Inputs, Digital Inputs and Digital Output are isolated from the other circuits.
Measurement accuracy is better than ±1%
Physical connection specifications:
• Cross sectional Area:
With ferrules: from 0.2 to 2.5 mm²
Without ferrules from 0.2 to 4mm²
• Tightening torque 0.4-0.5 Nm
• Stripping length/blade size: 7 mm / 0.6 x 3.5
2.5.5 Digital output (X4)
The digital output is a solid state relay controlled via the Modbus link.
Maximum voltage is 30Vdc/ac.
Maximum current is 50mA.
Physical connection specifications:
• Cross sectional Area:
With ferrules: from 0.2 to 2.5 mm²
Without ferrules from 0.2 to 4mm²
• Tightening torque 0.4-0.5 Nm
• Stripping length/blade size: 7 mm / 0.6 x 3.5
