jumpers J7 and J6.
Error: ±0.5% when output is 5V at 25°C
RO1A
RO1 output; RO1A: NO; RO1B: NC; RO1C: common
Contact capacity: 3A/AC250V, 1A/DC30V
RO1B
RO1C
COM
+24V common terminal
Y1
Switch capacity: 50mA/30V
Output frequency range: 0±1kHz
Y1 and S4 share the output terminal. The selection is made through J10.
485+
RS485 communication port, RS485 differential signal port and standard RS485
communication port must use twisted shielded pairs; the 120ohm terminal
matching resistor for RS485 communication is connected through jumper J8.
