AD7 Product Description

Connect the HD25A to the AD7 to have easy access to both the SEI bus and the analog output. The AD7 has both a power jack for plugging in a US Digital PS-12 power supply, and screw terminals for connecting a customer supplied power supply (5.5 to 16VDC). DIN-rail mounting is available. There is a 6-pin RJ-12 female connector to connect the AD7 to the SEI bus via an AD2B or SEI-USB. This in turn allows complete control of the HD25A via your PC. Analog+ and Analog- are available on a two position screw terminal plug / socket on the AD7.
