Alarm Signal/Relay Wiring
The instrument provides three relays, J6, J7 and J8 (see
Figure 3.6), without voltage contacts through the main
control board. Three contacts: normally open (NO),
normally closed (NC) and common terminal (COM). The
maximum rated capacity of relay contacts is 250V AC, 8A.
The maximum acceptable cable size for the wiring
terminals is 14AWG. Table 3.3 describes J6, J7 and J8
wiring terminals and corresponding functions.

Digital Signal Input Wiring
Two digital input interfaces on the main control board are
used for the external trigger control. Pin 1 and pin 2 of J2
and J3 are inputs. Either external power input or internal
power of the instrument can be used. If external power
input is used, the external power supply shall be 5~24V
DC. If the internal power of the instrument is used,

RS485 Communication Output Interface
The instrument provides an RS485 communication output
interface (See Figure 3.14) at the upper left of the
electronic cabinet through the single board computer, the
default baud rate is 115200. Please refer to Figure 3.15
and Table 3.5 for signal wiring.
