SS10188 - 8ch DI 8ch PNP Output Modbus RS-485 IO Module

Description

SS10188 – 8ch DI 8ch PNP Output Modbus RS-485 IO Module

The SS10188 is able to acquire up to 8 digital inputs with connection NPN or PNP and to drive up to 8 digital outputs type PNP transistor. 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 SS10188 is designed to work with the MODBUS RTU/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.
