HDA.ISO – Analog signal ISO for HDA 5500
The HDA.ISO signal consists of 6 measured values (START / ISO 4 / ISO 6 /
ISO 14 / ISO 21 / Status) which are output sequentially. Synchronization with
the downstream control unit is a prerequisite.
The signal output is as follows:
Measured variable
Signal duration
in s
Current/Voltage
Start signal 0 -- 2 20 mA / 10 V
Pause 2 4 mA / 2 V
Signal 1 ISO 4 2 Current / Voltage for signal
Pause 2 4 mA / 2 V
Signal 2 ISO 6 2 Current / Voltage for signal
Pause 2 4 mA / 2 V
Signal 3 ISO 14 2 Current / Voltage for signal
Pause 2 4 mA / 2 V
Signal 4 ISO 21 2 Current / Voltage for signal
Pause 2 4 mA / 2 V
Signal 5 Status 2 Current / Voltage for signal
Pause 30 4 mA / 2 V
