Datexel Digital Input Module on MODBUS RS485 - DAT3148/12

Name: Digital Input Module on MODBUS RS485 - DAT3148-12
Brand: Datexel
SKU: DAT 3148-12
Availability: OutOfStock

12 digital inputs, Watch-Dog alarm, CE mark, Highly Accurate – High Quality

The device DAT 3148/12 is able to acquire up to 12 digital inputs. The data are transmitted with MODBUS RTU/MODBUS ASCII protocol on the RS-485 network.

The device guarantees high accuracy and 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 3148/12 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 17.5mm only, allows a high density mounting on EN-50022 standard DIN rail.

COMMUNICATION PROTOCOLS

The DAT3148/12 is designed to work with the MODBUS RTU/MODBUS ASCII protocol: standard protocol in field-bus; allows to directly interface DAT3000 series devices to the larger part of PLCs and SCADA applications available on the market.

Digital Input Module DAT3148/12 comes with the following features:

Field-Bus remote data acquisition
Modbus Slave device on RS-485
Modbus RTU/ Modbus ASCII protocol
12 digital inputs
Watch-Dog alarm
2000 Vac galvanic isolation on all ways
High accuracy
UL / CE mark
In compliance to EN-50022 DIN rail mounting

Series Information

“DAT3000 SERIES” data acquisition and control modules

The distributed I/O modules of the DAT3000 series represent a complete solution for the acquisition and control of the analog and digital I/O signals.

The series is composed of:

Serial line converters and repeaters (DAT3580, DAT3580 USB, DAT3580 MBTCP, DAT3590).
Modules for digital inputs and outputs (DAT3130, DAT3140, DAT3148/8, DAT3148/12, DAT3188/4, DAT3188/8).
Modules for analog inputs (DAT3011, DAT3014, DAT3015, DAT3016, DAT3017, DAT3018, DAT3019).
Modules with analog outputs (DAT3022, DAT3024, DAT3028).

The devices communicate on the RS-485 serial line by the MODBUS RTU communication protocol and are able to communicate with the host computer on multipoint net using only two wires.
