Two 4-21 mA analog input card, with two thresholds that can be set through the panel keyboard.

It can manage gas detection systems, as well as level and temperature signal systems.

It can control all the 4-20 mA output transducers normally used for EXPLOSIVE and TOXIC GAS, OXYGEN, TEMPERATURE and LEVEL sensors.
