Digital Voltmeter JLD5740 pin assignment

Power 9-30V at Pin 1(+) and Pin 2(-)


Measurement current input (pin selection on PvH with Password:0036)
only use one + input
Pin 4 -up to +500V select on PvH with the number 500
Pin 5 -up to +100V select on PvH with the number 100
Pin 6 -up to +10V select on PvH with the number 10
Pin 7 -up to +1V select on PvH with the number 1
Pin 8 -negative pole

Current output at pin 9 (-) and pin 10 (+)
This is only needed when measuring current

Relay J2 at pin 11-13
(settings on AH2 and AL2 with Password:0001)
Pin 11-12 NC (normally-closed) Circuit is connected when the relay is inactive.
Contacts disconnect the circuit when the relay is activated (the lower LED is on).
Pin 12-13 NO (normally-open) circuit is disconnected when the relay is inactive.
Contacts connect the circuit when the relay is activated (the lower LED is on).


Relay J1 at pin 14-16
(settings on AH1 and AL1 with Password:0001)
Pin 14-15 NC (normally-closed) Circuit is connected when the relay is inactive.
Contacts disconnect the circuit when the relay is activated (the upper LED is on).
Pin 15-16 NO (normally-open) circuit is disconnected when the relay is inactive.

Contacts connect the circuit when the relay is activated (the upper LED is on)

  1. The current output pin 9 and 10
    is an OUTPUT with 0-20mA or 4-20mA
    that can be sent to some other equipment,
    like a charger.
    Normally 20mA mean 100% of the range.
    4 - 20mA Systems are normally used,
    if the sensor is supplied by the
    two signal wires.
    if You put a 250R resistor between the
    contacts, there should be a voltage of
    5V at 20mA at 100% of the range.
    Ideally, this output sends a current,
    otherwise the output only regulates
    the current.
