• Inactive = 0 to 5 V, active = 16 to 30 V
5.6 Output Signals
AO1, AO2, AO3
• Three analog outputs, 0–20 mA or 4–20 mA. Loading 0 to 650 Ω.
• Load dependence < 0.2 % for a change from 0 to 60 Ω.
DO1, DO2, DO3, DO4, DO5, DO6
• Six digital outputs, 24 V 250 mA.
5.7 Computer Communication
• RS485 serial interface, COMLI or MODBUS RTU protocol.
• RS232 serial interface, COMLI or MODBUS RTU protocol.
5.8 Safety Functions
Supply Failure
• Restart from present position (3-state pulse output) or a preset position.
Input/Output Signal Failure
• Failure of the analog input/output signal initiates an alarm.
5.9 Indications
