except that it is also equipped with sixteen LEDs. These are located
beside the module's panel.The purpose of an LED is to tell the user the
state in which the channel is in at the time. If the LED lights up, it
means that the channel is in Logic Level "1". If the LED remains dark, it
means that the channel is in Logic Level "0". This is illustrated in the
table on the following page.
