5- 4. Connections
The MS-80 and MS-80U have an analog output for irradiance and detector temperature measurements. The MS-
80S is based on a digital Smart processing interface providing advanced measurement functions with 4 different
industrial signal outputs (Modbus 485 RTU, configurable SDI-12, 4-20mA, configurable 0-10mA and 0-1V with
external precision shunt resistor 100Ω).
