A.5 Programmable expansion card (SPC502-00) function description
SW1 is the start/stop switch of the programmable expansion card. CN1 contains terminals PE, 485-,
485+, GND, AI1, and AO1, and a selection jumper resides on the next. "AI" and "AV" are the current
type input selection and voltage type input selection of AI1, and they can be selected through J2. "AIO"
and "AVO" are the current type output selection and voltage type output selection of AO1, and they
can be selected through J5. "120" indicates 120Ω terminal resistor, and it can connect to J1. By default,
J1 connects to NC, J2 to AV, and J5 to AVO.
The terminals are arranged as follows:
