The DAT3130 manufactured by DATEXEl is a distributed I/O module that is specially engineered to achieve a maximum of four digital inputs and can drive four relay outputs. This module makes use of a MODBUS RTU/ASCII protocol on RS_485 network to transmit information. It is characterized by its safe operation system and is integrated with two watch-dog timers that signals when the outputs are forced automatically on the safe configuration.
The DAT3130 employs a 2000 Volt alternating current isolation between inputs. outputs, power supply. Its RS-485 eradicates ground-loop effect noise making this module suitable to use in any unfavorable operating conditions.
