ETA-SEQ6
Sequencer Controller
Rear Panel Description
TSD Input/Output connections are removable for easy system wiring. The connectors have a 3.5mm
pitch between pins.
1. DC Power Input - Each TSD that requires DC power comes with a 2 position connector for an
external 24VDC power supply (sold separately). Because of the TSD’s low power consumption, a
single external power supply may power more than one TSD. Please refer to the specications
on current requirements in milliamps to match with the appropriate power supply. Please observe
the polarity of the wiring to this connector. Note: It is acceptable to exceed the current
requirements of the TSD but NOT safe to use a power supply that is below the current
requirement of the device. Use a power supply with a 500mA capacity (Atlas TSD-PS24V500MA).
2. Channel Output - There are 6 channel output control ports. Each output can be assigned to provide
a 24VDC output or a Hard Switch Contact Closure (CC). See the Function Settings for Output
conguration below.
3. Remote Activation Momentary Switch Port - Remote System activation can be done several
hundred feet away via a momentary contact closure type switch.
4. Remote Activation Hard Switch Contact Closure (CC) Port - Remote System activation can be
done several hundred feet away via a Hard Contact closure type switch.
5. Remote Activation 5 - 24VDC Port - Remote System activation can be done several hundred feet
away by applying 5 - 24VDC. Only a few milliamps of current is required.
6. Link Control Port - You can combine two ETA-SEQ6 units together to make a 12 step sequence
system. Note: Pay special attention to the Input and Output terminals. Connect the Output from
unit 1 (Master) to the Input of unit 2 (Slave). Connect the Output from unit 2 (Slave) to the Input of
unit 1 (Master). Pay close attention to this or the Link Out will not work. See the Function Settings
for the Master/Slave conguration below.
