The SS3018 IO Module is able to acquire up to 8 analogue input signals. Data values are transmitted with MODBUS RTU/ASCII protocol on the RS-485 network (RS232 interface is available.)
Connect Thermocouples or up to +/- 1V voltage signals. The Cold Junction compensation for thermocouples is performed internally. The 16 bit converter guarantees high accuracy and stable measurements versus time and temperature. Furthermore, to ensure safety, two Watch-Dog timer alarms are provided.
The 2000 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.
The SS3018 is compliant with the 89/336/EEC directive on electromagnetic compatibility. The device is housed in a rough self-extinguishing plastic container. Additionally, with its thin profile of only 17.5mm, you can mount the device on a high density EN-50022 standard DIN rail.
The SS3018 is designed to work with the MODBUS RTU/ASCII protocol: standard protocol in field-bus. Furthermore, you can directly interface SS3000 series devices to most PLCs and SCADA applications available on the market.
