The Panel-Mount 1781-7B04 and DIN-Rail Mount 1782-7B04 are 4-channel backplanes for use with the 1781-7B Series, WRC7 Series or compatible signal conditioner line. Both backplanes are powered by a user supplied 24 V dc power supply with primary and secondary recepticles for uninterrupted operation. One 25-pin D-type connector provides a connection to the “logic” side of the 1781-7B04. Field-side terminations are achieved with screw terminations. For the 1781-7B04, 3/4″ standoffs are provided for panel mounting. DIN-rail mounting is provided for the 1782-7B04. The 1781-7B04 Mounting Board is fuse protected through F1. If the input supply voltage connection is reversed, diode DI will be forward biased to protect the modules. Provision is available for a user-provided, second, 25-pin, D-type connector.
