To communicate by I

C position left of the power SIP connector. The

C setting is default on the LK162-12.

Connector pinout is as follows:

1 2 3 4

Pin 1 Vdc

Pin 2 SCL (I

C clock)

Pin 3 SDA (I

C data)

Pin 4 Ground

2.2 General Purpose Outputs

The LK162-12 has seven general purpose outputs. These are provided to control relays or other electronic

devices. This allows external devices to be turned on or off using your PC or controller and software

commands. (See sections 6.1.10 and 6.1.11 for the command syntax.)

Each output is wired as shown in Figure 2-8. The + terminal is connected directly to the module positive

supply, the – terminal is connected through a 240 ohm current limiting resistor and the electronic switch to

ground.
