The ISO401-1 signal isolation module is designed to be mounted on a RGA Series drive (included with RGAxx3 models). The isolation module allows a user to safely connect a grounded or ungrounded signal to a RGA Series drive. The ISO401-1 module can accept current signals in the range of 1-50 mA or DC voltage signals in the range of -250 to +250 VDC. The output is easily scalable from -10 to +10 VDC via high resolution multi-turn trim pots. Isolation is achieved using highly linear Burr-Brown isolation technology. With cage clamp terminals for all connections and 115 or 230 VAC voltage capability, the ISO401-1 is ideal when the need arises to isolate signals from sensors, PLCs or computers.
