LDSBus Isolated IO Controller

Datasheet

The LDSBus Isolated IO Controller offers 2

isolated channels of digital and analog inputs and

a variety of associated power source options to

achieve 3.3V, 5V, 10V, 12V referenced signals

besides sourcing power from external voltage

sources. Each channel (input and output) is

isolated from the others.

Each digital output can switch between 0V and

3.3V, 5V, 12V or referenced to an external

voltage source. Each digital input can be between

0V and 1.8V to 12V. A 5V voltage source is

provided for common applications that switch

between 0-5V.

Each analog output can produce a voltage

between 0-10V, and each analog input supports

voltage or current controlled input sources

ranging between 0-10V.

The controller may be used in numerous and

diverse applications such as simple IO control, or

0-10V dimmers, weather station, water level

detector or sensor, etc.

5Isolated IO Controller Configuration and Installation

Please visit https://brtsys.com/resources to access the LDSBus Configuration Utility guide on

how to configure the device name, device address and termination settings before using it in your

application.

5.1 Connection Diagram

Figure 2 illustrates the connection of the LDSBus Isolated IO Controller (LDSBus Device) to the

LDSBus. Please visit https://brtsys.com/resources to view the full device application, setup and

installation guides.

Figure 2 - LDSBus Isolated IO controller - Connection Diagram

Setup Instructions:

1. Connect the first LDSBus HVT-Junction to any of the LDSBus Host Systems using a

RJ45(CAT5e) cable.

2. Connect the configured LDSBus Isolated IO controller to the LDSBus HVT-Junction as shown in

Figure 2.

3. If there is more than one LDSBus HVT-Junction, chain them together as shown in Figure 2.

4. Enable terminator on the last device in LDSBus.

7Terminal Wiring Instructions

Terminal blocks are connected with screws. To clamp the wire to the terminal block, insert a

0.4mm x 2.5mm slotted screwdriver and rotate in a clockwise direction. To release the wire, turn

the handle in an anticlockwise direction.
