Nomenclature:
SS200
Sensor supply output; KL30 level, max. current 100 mA, (fuse 350 mA)
OIN1…2
Optical isolated current sink inputs;
activated at voltage > 5VDC, internal limited current 4.5 mA
DIN1…2
Digital current sink inputs;
- activated by current > 3 mA,
- deactivated by current < 2.5 mA, internal limited current 4.5 mA
An open or deactivated input DIN1 cuts off relay output REL1 !
DIN3…4
Digital voltage inputs;
- activated by voltage with more than half level of KL30 +1 V
- deactivated by voltage with less than half level of KL30 –1 V
Input resistance 20 kΩ
FIN1…2
Frequency measurement inputs
- activated by voltage higher than 25% level of KL30
- deactivated by voltage lower than 15% level of KL30
Hysteresis 0,2 V, input resistance 44 kΩ
The FIN inputs should be connected to sources switching between high
and low, they should not be connected to sources switching between low
and open. f
max
20 kHz
AIN1…2
Analogue input, range 0…10 V, Input resistance 44 kΩ
AIN3…4
Analogue input, range 0…5 V, Input resistance ≥ 1 MΩ
AGND
Analogue Ground, reference level for AIN1…4
IConst1…2
Constant current outputs for PT100 sensors, 22 mA
- active only while measuring –
PT100 sensors have be connected to AIN3, AGND and IConst1 - or -
AIN4, AGND and IConst1 -2.
