HUST H2N Connecting Manual

5.2 Input Board and Output Relay Board
The input signal connection can be done in two ways:
1. Connect directly to DB25LF connector in the controller shown in Fig 5-1.
2. Connect input signal to the corresponding terminal of HUST input board, then
connect from DB25LF connector on the board to the connector on the controller
box. HUST input board is shown in Fig 5-2. The advantage of using input board
is to protect the controller circuits from being damaged in case of short circuit.
This method of connection is suitable for NPN-type input connector only.

The output signal connection can also be done in two ways:
1. Connect directly to DB25LM connector in the controller shown in Fig 5-1.
2. Connect output signal line from external device to the corresponding terminal of
output relay board, then connect from DB25LM connector on the board to the
connector on the controller box. HUST output board is shown in Fig 5-3. The
