A conveniently packaged Din rail mounted AC voltage to an adjustable 0-10VDC output module. Designed specifically for “HAND / OFF / AUTO” applications for BMS controller inputs, when in “HAND” a DC voltage needs to be forced into BMS input cards, but not necessarily a full 10VDC signal is required. This product can be specified with either a 24VAC, 24VDC, 110VAC or 230VAC primary voltage, the output voltage is an adjustable 0-10VDC via a front mounted potentiometer. A healthy AC input voltage is signalled by an illuminated green LED, and the output voltage is indicated by an increasing in intensity illuminated red LED starting at 1VDC (below 1VDC the output will be present, but without LED indication). Note this product is not designed to power “control circuits”, it is only for driving into BMS input cards, max 10mA @ 10VDC.
