SS10148 - 16ch DI Modbus RS-485 IO Module

Description

SS10148 – 16ch DI Modbus RS-485 IO Module

The SS10148 is able to acquire up to 16 digital inputs with connection NPN or PNP. 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 the use of the device even in the heavy environmental conditions.

The device is housed in a 6 module DIN rough self-extinguishing plastic box for mounting on EN-50022 standard DIN rail.

The device is designed to work with the MODBUS RTU/MODBUS ASCII protocol: standard protocol in field-bus; allows to directly interface SS10000 series devices to the larger part of PLCs and SCADA applications available on the market.
