The Vaisala Indigo520 transmitter with dual-probe and multi-parameter support is a host device for Vaisala Indigo-compatible, stand-alone smart probes. The transmitter offers many additional features to the Indigo probes.
The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends connectivity, supply voltage, and wiring compared to a smart probe. It also provides mechanical support when wall-mount probe installation is preferred. Rugged IP66- and NEMA4-rated metal enclosure ensures reliable performance even in the harshest conditions.
Variety of probe options
Vaisala Indigo520 transmitters are the most versatile option for use with Indigo-compatible smart probes.
- Humidity and temperature probes:
HMP1, HMP3, HMP4, HMP5, HMP7,
HMP8, HMP9, and TMP1
- Dew point probes: DMP5, DMP6, DMP7,
- CO2 probes: GMP251, GMP252
- Vaporized hydrogen peroxide probes:
- MMP8 moisture in oil probe
Analog and digital interfaces
The transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. Indigo500 can assign any of the output parameters from the connected probes to control the analog channels and relays. The digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter’s Ethernet connection provides a web interface and cybersecurity that meets modern standards.
