Digital Input Module (DIM)
General Description
Eaton’s Cutler-Hammer Digital Input
Module is a device that inter-faces with
up to four standard utility (electric,
gas, water) meters or monitors eight
digital inputs. It translates KYZ pulses
from meters into a register count that
is maintained and compiled within the
DIM module in non-volatile memory.
The pulse count can be accessed from
the DIM module remotely using Cutler-
Hammer Power Management Software
including the Energy Billing application.
The DIM can also be used to
monitor eight digital inputs from
switch closures.
Application Description
■ Reads four separate KYZ equipped
utility meters.
■ Pulse counts stored in non-volatile
memory.
■ Each channel independently
monitors KYZ counts, pulse counts,
or digital indications.
■ Monitors a maximum of eight
individual digital inputs.
■ Input channels are isolated.
■ Isolated 24 Vdc power is provided
on the I/O connector.
■ LED indicators on the input channels
indicate when the unit is counting.
Physical Characteristics
■ Height: 4.25 inches (107.9 mm)
■ Width: 3.54 inches (89.9 mm)
■ Depth: 3.50 inches (88.9)
(does include DIN rail)
■ 10 LED status indicators, 100 ohm
termination DIP switch, address
selector switches
■ DIN rail mounting

Mounting Information
The DIM module is designed to be
DIN rail mountable. DIN rail must
be 1/3 inches H X 1-3/8 inches W
(8.5 mm H x 34.9 mm W).
Communications
The DIM is a fully compatible Power
Management Software communicating
device with built-in INCOM commu-
nications. The DIM comes complete
with a 3-pin connector to receive the
shielded twisted pair conductor.
All wiring must be complete as per
Instruction Leaflet TD17513, Wiring
Specification Base Rules.
