Note 2. Output Parameters
• Sensor input circuit (Terminals 1 to 5 )
Uo: 6.6 V
Io: 66 mA
Po: 109 mW
Co: 22 μF
Lo: 8.1 mH
• For the sensor input circuitry, these entity
parameters must be taken into account when
installed.
• The above parameters apply when one of
the two conditions below is given:
- the total Li of the external circuit (excluding
the cable) is < 1% of the Lo value or
- the total Ci of the external circuit (excluding
the cable) is < 1% of the Co value.
• The above parameters are reduced to 50%
when both of the two conditions below are
given:
- the total Li of the external circuit (excluding
the cable) is ≥ 1% of the Lo value and
- the total Ci of the external circuit (excluding
the cable) is ≥ 1% of the Co value.
• The reduced capacitance of the external
circuit (including cable) shall not be greater
than 1μF for Group IIB and 600nF for Group
IIC.
Note 3. Installation
• Installation should be in accordance with
local installation requirements.
