The Procon Electronics Prologic PL8AO is a current output module that supplies analogue signals from a marine control system to connected field devices. It provides eight analogue outputs at 0-20 mA DC, with a switch-selectable 4 mA offset for 4-20 mA operation, and a resolution of 12 bits (0-4095). Accuracy is 0.05 % of span, typical drift is 100 ppm/°C, and the outputs drive loads up to 1000 ohms at 24 V DC. Field and logic circuits are isolated at 1500 V AC RMS, and the field side takes a +24 V DC supply. The module is supplied in New Without Box condition.
