DESCRIPTION
The LMIO-101 Digital Input/Output Interface allows seamless integration of 3rd party devices to the Wattstopper Digital Lighting
Management Local Network (DLM). The LMIO-101 connects to the DLM local network. It sends messages such as After Hours, Shed,
or Force On to the DLM local network based on external inputs. It also activates the isolated relay upon any signal from any user
defined DLM occupancy sensor so that a 3rd party’s device can observe when occupancy is detected. It also has a 24VDC output and
pilot light function.
OPERATION
The LMIO-101 operates on power from the DLM local network. It contains a 24VDC isolated relay
[single-pole, double throw with normally open (N/O), normally closed (N/C), and common outputs for
output to other systems. It also provides input terminal connections and options for converting input
signals from 3rd party devices into load controlling messages for the DLM system.
Outputs: Isolated Relay, 24VDC, Pilot Light
The isolated relay can respond to any DLM occupancy sensor on the DLM local network to provide
the DLM system’s occupancy status from a specific sensor to a third party controlling device, such as
HVAC or other controlling systems.
The LMIO-101 also provides 24VDC, 5mA current limited, output and a pilot light terminal.
Inputs
Four input terminals are provided for purposes including Force-ON/Force-OFF,
load shedding and cleaning functions. Input terminals 1A, 1B, 2A and 2B are
for connection of maintained or momentary switch closure inputs, or third party
logic inputs. Input signals may come from a wide variety of devices including
building automation systems, time clocks, and key switches.
DIP Switch Options
The LMIO-101 has DIP Switches to allow different messages to go out from third party switches to the DLM local network to control the
loads bound to the LMIO-101.
With the default DIP Switch setting (all
OFF
), using Inputs 1A and 1B or 2A and 2B the LMIO-101 can take an input from any of three
types of switches: Momentary
ON/ OFF
, Maintained or Momentary push button. When these inputs receive a 24VDC signal, the
LMIO-101 issues a DLM command to turn
ON
the loads bound to the input.
When the DIP Switches are changed to a non-default setting, the LMIO-101 sends the appropriate digital command on the local
network as determined by the DIP Switch settings when receiving a dry contact closure input to either 1A, 1B or 2A.
