Input stage of Dx channels consists of a circuit for connection of dry contacts. This stage continuously provides 5V voltage at the terminal. In input mode the Tx key is inactive (open). When the terminal is grounded, small current (2 mA) flows via the channel. Controller considers that as triggering of the input. Closing of the Tx key is considered as triggering of the input. In output mode the output stage does not affect the channel operation, provided that a more than 5 V load is connected to the channel.
