HH and COMMON are short-circuited by relay.
H and COMMON, L-COMMON, LL-COMMON are short-circuited in the same
manner.
[Caution] Provide the surge protection in case the induced load is driven.
5) Wirings for 4-20mA output
A11 and A12 are used for the output of the level difference between CH1 and CH2.
6) Wirings for RS-485
Use the shielded twisted pair cable for RS-485 line. Connect the shield to FG, A5.
