Machine monitoring in Hazardous Area

I am looking for a machine monitoring system to be used in Zone-2 IIB T4 hazardous area. The system should accept 16 RTD signals, process them with individual cards dedicated to each channel, generate alarm and trip contacts for each channel. It should also have display of current value for each channel and facility to adjust alarm and trip values in the field itself. The system is also desired to have retransmission 4-20mA signal for each channel. Please suggest if such a product exists as my efforts to search for such a product went in vain.
