AC/DC Converter AT-VA2-D-A3-DD-ADL 1. Product Description The AT series converter/distributor is mainly designed for conversion and isolation in general signal loops; such as 4~20mA, 0~10V, thermocouple (Type K, J, E, T), thermal resistor (Rtd-Pt100Ω), load cell, potentiometer (three-wire), resistor (two-wire) and AC voltage/current signals, with a full range of models. This thin-designed converter/distributor not only provides two sets of signal outputs (isolation between outputs) or 24V excitation power for transmitter use, but also provides installation convenience through switching power supply. The power, input and output indicator lights and pluggable terminal blocks are designed on the top to facilitate on-site construction and working status inspection. 2. Product Features You can choose to switch with a dip switch. Six conventional output signals 0-5V/0~10V/1~5V/2~10V/4~20mA/0~20mA can be switched by yourself. The dual-circuit output is completely isolated and different signals can be selected. Power, input and output LED indicators are designed to facilitate on-site working status inspection. You can specify 0.1% accuracy 17.55mm thin 35mm rail installation in the specification selection table. Designed according to CE international standards. 3.
