Model 1008 LED Dimmer
REV 2
Manual
CONNECTIONS
OVERVIEW
The Pathway eDIN LED Dimmer/DC Driver provides
DMX512 control over LEDs and other DC devices.
Each module provides 6 channels of control.
When controlling LEDs, the module acts as a
dimming interface only. The LED fixture will require a
separate
regulated
DC
power
supply,
as
recommended by its manufacturer.
These instructions apply to REV 2 modules.
eDIN LED Dimmer/DC Driver modules feature terminal
strips that can be removed from the module to facilitate
wiring and replacement. Make the following connections
WITH THE POWER TURNED OFF:
POWER
The module is designed to run on a range of voltages
from 9 to 30 VDC, at 500mA per card connected.
Observe the correct polarity when connecting to V+
and V-. A second set of terminals is provided on the
same connector to daisy-chain power to other eDIN mod-
ules. Earth Ground must be connected to the enclosure’s
chassis or ground terminal to ensure EMC compliance.
DMX512
DMX connections consist of a shield wire and one or
two data pairs. DMX IN is wired from the control console,
or other source. DMX THRU may be daisy-chained to the
DMX IN of other eDIN cards, or to other DMX equipment.
Connect DATA+ and DATA– wires to D1+ and D1-
respectively. The optional data pair may be connected to
D2+ and D2-. Observe the same polarity convention
throughout the system. Connect the shield wire to the
SHLD/COM terminal.
DC/PWM OUTPUTS
The LED Dimmer/DC Driver interface provides six (6)
outputs that will each handle up to 4 amps at voltages up
to 30VDC. The outputs are of the current-sinking type. A
separate DC power supply is required, appropriately sized
for the connected load, as recommended by the con-
nected equipment’s manufacturer.
‘DMX PRESENT’ RELAY CLOSURE
Each output is fully opto-isolated from the other out-
puts, from the DMX signal and from the eDIN board
power supply. Multiple pins are provided to allow for load
spreading. Outputs are connected as follows:
LOAD- (Terminals 1 & 2): Connects to the negative termi-
nal of the load, or the LED Cathode.
V- (Terminals 3 & 4): Connects to the negative or com-
mon terminal of the load power supply.
V+ (Terminals 5 & 6): Connects to the positive terminal of
the load power supply and to the positive terminal of the
load, or the LED Anode.

OUTPUT RATING

Internally Fused @ 4A/Output
(2 Spare Fuses Inside)
POWER IN
9-30VDC
Max 4 Watts
Wire RCOM to RNC or RNO for a normally closed or
normally open DMX indicator, as desired.
When DMX is present, the closure will be held in a
state opposite to its ‘normal’ position.
CONTACT CLOSURE ‘PANIC’ INPUT
When CCL is shorted to IN-GND, for example by clos-
ing an e-stop switch, all outputs are forced to the MAX
output level, regardless of DMX level or signal presence.
ANALOG INPUT
Applying a 0-10VDC input between any AIN(x)
and the IN-GND pin will drive that particular output. Out-
put level is an HTP-merge between the DC voltage level
and the incoming DMX signal for that channel.
Do not exceed 10VDC maximum input voltage.
