SS 3148 Distributed I/O module 8+4 digital inputs on RS-485 network

In stock
Digital module with 12 digital inputs

General description

The device SS 3148 is able to acquire up to 12 digital inputs. The data are transmitted with MODBUS RTU/ASCII on RS-485 network.
The 2000 Vac galvanic isolation between inputs, power supply and RS-485 serial line cancels any ground-loop effect noise, allowing the use of the device in worst ambient conditions.
The SS 3148 is in compliance to the 89/336/EEC directive on the electromagnetic compatibility.
The SS 3148 is housed in a rough self-extinguishing plastic enclosure of 17,5 mm thickness, suitable for EN 50022 standard DIN rail.
