Description

Datexel Isolated Module Modbus Digital Input Module - DAT3148/8

8 digital inputs, Watch-Dog alarm, DIN rail mounting, UL / CE mark - High Quality

The device DAT 3148/8 is able to acquire up to 8 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 3148/8 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 DAT3148/8 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.

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
