Datexel Isolated Module Multiple Input, Current Output - DAT3011

1 SSR Digital Output + 2 SPST Relay Outputs, Watch-Dog Alarm, UL/CE Mark – Italian Made

The DAT 3011 device is able to acquire RTD or Tc sensors, mV, V or mA input signals connected to the universal analogue input in engineering units in digital format.

Moreover, it is available a second isolated analogue input for V or mA. The device is able to acquire up to 3 digital inputs and to drive one solid-state relay and two SPST relays. The Data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network.

The device guarantees high accuracy and a stable measure versus time and temperature. To ensure the plant safety two Watch-Dog timer alarms are 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 DAT 3011 is in compliance with the Directive UL 61010-1 for US market and with the Directive CSA C22.2 No 61010-1 for the Canadian market.

The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5mm only, allows a high density mounting on EN-50022 standard DIN rail.
