A.6 Programmable extension card (EC-PC502-00)
In this figure, SW1 is the start/stop switch of the programmable extension 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.
