Distributed control system NL-Ex series with intrinsically safe circuits (i) for automation of technological processes on explosive industrial objects

The control system below includes input-output modules with intrinsically safe circuits and can be used in conjunction with PLC NLcon-1AT-Ex or any computer or PLC (e.g. NLcon-CE), if they located in the safe area and connected to the intrinsically safe parts trough safety barrier or interface converter NL-232C-Ex. A series of NL-Ex has certificate of conformity to industrial safety requirements in accordance with Russian GOST R 51330.0-99, 51330.10-99 GOST, GOST R 51330.20-99.

The modules below are software compatible with similar module of ADAM, ICP and use standard Modbus RTU or DCON protocols.
