8ch DIO 4 Relay Modbus RS-485 IO Module, SS10130 from Sielco Sistemi.

The SS10130 allows you to acquire up to 8 digital inputs with NPN or PNP connection. It also drives up to 4 relay outputs – 2 SPDT format and 2 in SPST format. The data are transmitted with MODBUS RTU/ASCII protocol over the RS-485 network.

To ensure the plant safety, a Watch-Dog timer alarm is provided. The isolation between the parts of circuit removes eventual ground-loop effects, allowing you to use the device in heavy environmental conditions.

In addition, the SS10130 is housed in a 6 module DIN rough self-extinguishing plastic box allowing you to mount on EN-50022 standard DIN rail.

The device 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.
