3.0 CONNECTING METERS TO THE IDR
(CONTINUED)
Third-Party Meter Connections
In order to connect “third-party” meters such as gas, water or utility-type meters, the
IDR must be ordered with the “two-screw” connectors (designated with the suffix ST at
the end of the model number) terminals instead of the modular jacks that are used with
E-Mon D-Mon meters.
The input pulses supplied to the IDR must be non-powered. Pulses can be either
physical (mechanical) contacts or electronic switches. When electronic switches are
used, the left terminal on the IDR is the “+” output and the right is the return from the
switch.
