SS3024 – 4ch V – mA Modbus RS-485 IO Output Module from Sielco Sistemi.
The SS3024 IO Module generates up to 4 output analogue signals from digital commands. Data values are transmitted with MODBUS RTU/ASCII protocol on the RS-485 network (RS-232 interface is available).
It is possible to generate voltage signals up to 10V and current signals up to 20mA, both active or passive loops. By means of a 16 bit converter, the device guarantees a high accuracy and a stable measure versus time and temperature. To ensure the plant safety, two Watch-Dog timer alarms are provided. The 2000 Vac isolation between input, power supply and serial line removes undesired ground-loop effects, allowing the use of the device even in the heavy environmental conditions.
SS3024 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 SS3024 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.
