Vaisala Indigo500 Series - Output Options; Analog Outputs; Digital Output

2.7 Output options
The Indigo510 transmitter provides 2 analog output channels and an Ethernet connection for
the Modbus TCP/IP protocol and web interface.
The Indigo520 transmitter provides 4 analog output channels, 2 relays, and an Ethernet
connection for the Modbus TCP/IP protocol and web interface.
If the Indigo520 transmitter is powered using Power over Ethernet (PoE), analog
outputs and relays are not available.
2.7.1 Analog outputs
The Indigo510 transmitter provides 2 scalable analog output channels with voltage or current
output.
The Indigo520 transmitter provides 4 scalable analog output channels with voltage or current
output.
Available analog output modes:
• Voltage: 0 … 1 V, 0 … 5 V, 0 … 10 V
• Current: 4 … 20 mA, 0 … 20 mA
Use the touchscreen or web interface to configure the output mode for the channels (same
output mode in all channels), as well as the measurement parameter and scaling for each
channel.
Analog outputs are not available in transmitters that are powered with Power
over Ethernet (PoE).
