Optional Input Electronics Wiring

The meter has two optional input wiring terminals. These can be used to input a Remote or Second RTD input in the case of an Energy Monitoring meter, for the input of a Remote Pressure Transducer, to pass a Contact Closure or for a Remote Density measurement to name a few. In any case, the wiring diagram will be included with the meter if any of the op- tions are specified. Otherwise, the optional terminal blocks will be left blank and non functional.

Optional Energy EMS Input Electronics Wiring

The recommended customer supplied second RTD is a Class A 1000 ohm 4-wire platinum RTD. If a second RTD is not being used, then the fac- tory supplied 1000 ohm resistor needs to be installed in its place.
