| Universal I/O module with RS485 interface, 1 Universal Analogue Input + 1 Analogue Input V/mA - 2 Analogue Outputs 0-20mA - 3 Digital Inputs with pulse counters up to 3 kHz - 1 SSR Digital Output + 2 SPST Relay Outputs | ||
Description
The device DAT 3011 is able to acquire RTD or Tc sensors, mV, V or mA input signals connected to the universal analog input. Moreover a second V/mA analog input is available.
The device is able to acquire up to 3 digital inputs and to drive one solid-state relay and two SPST relays.
Data values are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network.
By means of a 16 bit converter, the device guarantee a high accuracy and a stable measure versus time and temperature.
To ensure the plant safety, two Watch-Dog timer alarms are provided. The 1500 Vac isolation on all ways (Power Supply / RS485 / Universal input / V-mA input / Digital inputs / Relay outputs) removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.
