LT3504

The LT3504 is an addressable relay module with 4 channels, each relay channel has a capacity of 200V/20A. It has a small compact enclosure and is easy to wire up and connect. It is most often installed in subpanels and used with air circuit breakers.

LT2504/8

Both the LT2504 and LT2508 are external relay controllers, with each having 4 and 8 channels respectively. The external relay is an LR02 latching relay with 20A capacity.

LT3100

The LT3100 is an addressable relay controller with 4 channels for controlling magnetic contactors, but unlike ordinary addressable relays, each channel also has inputs for the auxiliary contacts of each MC including its on/off status, local/remote status, and overload trip status. It can then synchronize the MC status to all the IS digital switches and touch panels connected to the D-Bus network.

LT3000

The LT3000 is well suited for the lighting control in classrooms, offices, libraries, conference halls, hallways, restrooms and other places that require local on-site user control, but also require centralized control. Since the LT3000 can be used with classic switches, then any switch can be selected that will best match the interior design or motif; in addition, classic switches are durable and reliable.

  • The LT3000 is specificially used for on-site applications for use with classic mechanical switches, it has 4 channels, each with built-in 220VAC/10A relays.
  • The digital inputs of the LT3000 can be connected to rocker switches, push buttons, K15 sensor or any other device with a dry contact output (such as a temperature switch).
  • Can also be configured to have a delay time for use during auto off.
  • Four of the digital inputs can also be connected to either safety detection sensors or emergency help buttons that can be monitored by a central host.
  • The LT3000 has no priority control, both central host and local contral have equal access.

LT4500

The LT4500 has four 0~10V analog outputs, which can be connected to four dimmable power supplies for use with dimmable fluorescent lights, LED lamps or any dimmable power supply (such as the K80) that accepts 0~10V as an input signal.

The LT4500 also has four ports for connecting with potentiometers for use with dimming knobs. Commands from the D-Bus can be issued to adjust the dimming outputs, but the dimming knobs can still be used to manually adjust the lights at any time.

LT3384

The LT3384 is well suited for the lighting control in classrooms, libraries, hallways, restrooms and other places that require local on-site user control, but also require centralized control. During peak hours, the lights would be controlled from central control, while control will revert locally using switches or sensors.

The LT3384 can be used with classic switches with its variety of designs to match any interior decor. Instead of switches, the LT3384 can also make use of sensors for control instead. When central authorizes it, then the local switches or sensors are allowed to be used.

  • The LT3384 is specificially used for on-site applications for use with classic mechanical switches, it has 4 channels, each with built-in 220VAC/10A relays.
  • The digital inputs of the LT3384 can be connected to rocker switches, push buttons, K15 sensor or any other device with a dry contact output (such as a temperature switch), the switch or sensor connected to the LT3384 can directly control the relays, and also be synchronized with the other digital switches on the same network.
  • When needed the auto off delay time can also be set.
  • Four of the digital inputs can also be connected to either safety detection sensors or emergency help buttons that can then be monitored by a central host.
  • The LT3384 has an authorization mode of control, in which the local control would only be allowed if the central control authorizes it.

LT4544

The LT3384 is well suited for the lighting control and energy saving through dimming for classrooms, libraries, hallways, and restrooms. The LT3384 is often connected to a central host that takes complete control during peak periods, but reverts control to local switches and sensors during off-peak periods.

  • The LT4544 has four 0~10V output channels for connecting to four dimmable power supplies, but can also be used with dimmable fluorescent lights, LED lamps or any dimmer driver that can accept a 0~10V input signal (such as the K80).
  • The LT4544 has four switch inputs for use with switches or sensor for local control.
  • The central host can choose to allow for equal access or authorized access.
  • The LT4544 only has four inputs and is thus unlike either the LT3000 or LT3384 in that it cannot connect to safety detection sensors for the purpose of warning alerts.
