A total of 18 outputs (1-18), contact capacity: AC220V/DC30V,5A.
It can be directly connected to low-power resistive loads and
low-power AC/DC inductive loads (such as AC contactor and DC
contactor). See the following figure for the wiring method. If
the load power is large, please relay in series to prevent the
instrument from being damaged.

This instrument can be connected to one or two large-screen
displays. Note that this interface is multiplexed with the OC gate
output port, and only one function can be selected. If you want
to use this function, you must first set the parameter F37. See
Section 7.3 for details.
