4ch RTD Modbus RTU-ASCII RS-485 IO Module, SS10014 from Sielco Sistemi.
The SS10014 RTD IO Module allows you to acquire up to 4 RTD input signals. These data values are transmitted with MODBUS RTU/ASCII protocol on the RS-485 network.
You can connect RTD , Potentiometers or Resistance signals. This device has many benefits. Firstly, the SS10014 guarantees you a high accuracy and stable measurement versus time and temperature. Two Watch-Dog timer alarms are also provided to ensure the plant safety. Additionally, the 1500 Vac isolation between input, power supply and serial line removes eventual ground-loop effects. This allows you to use the device in heavy environmental conditions. In addition, the device is housed in a 6 module DIN rough self-extinguishing plastic box allowing you to mount on EN-50022 standard DIN rail.
The SS10014 is designed to work with the MODBUS RTU/ASCII protocol, a standard protocol in field-bus. This allows you to directly interface SS10000 series devices to many of the PLCs and SCADA applications available on the market.
For the protocol and installation instructions, please see the Product specifications sheet and user manual.
