With this 4ch Modbus RS-485 IO Module, it is possible to connect RTD , Potentiometers or Resistance signals. By means of a 16 bit converter, the device guarantees a high accuracy and a stable measure versus time and temperature. Furthermore, to ensure the plant safety, two Watch-Dog timer alarms are also provided. Additionally, the 2000 Vac isolation between input, power supply and serial line removes eventual ground-loop effects. As a result, the device can even be used in heavy environmental conditions. SS3014 is in compliance with the 89/336/CEE directive on the electromagnetic compatibility. The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 17.5mm only, allows a high density mounting on EN-50022 standard DIN rail.
The SS3014 is designed to work with the MODBUS RTU/ASCII protocol: standard protocol in field-bus; allows to directly interface SS3000 series devices to the larger part of PLCs and SCADA applications available on the market.
