Hello,
The best i could find was the following...
Pins 1 to 5 are for Iin the current to be measured input pins,
pins 6 to 10 are for Iout the current to be measured output pins,
the pin marked "+" is for the positive voltage supply which +15v dc,
the pin marked "-" is for the -15v supply voltage (the -15v supply negative lead),
Zero volts would then be the common connection of the +15 and -15 supply voltages.
the pin marked "O/P" is the output which goes to RM and the other lead of resistor RM goes to zero volts (ground).
The nominal coil resistance is 110 ohms at 70 degrees C.
Output signal is 25ma for 25 amps. The load resistor goes from output to ground which is zero volts.
The unit is for 25 amps RMS current max. The case is polycarbonate plastic.
If there are no physical markings as above then hold the case in front of you so you can see the bottom clearly. Orient the case so that the three wide spaced pins are on the bottom. The pin numbering is then as follows...
On the top row of 5 pins, they are numbered from left to right 1,2,3,4,5,
on the middle row of 5 pins they are numbered from left to right 10,9,8,7,6,
and the bottom three pins are identified from left to right as "-","+', "O/P".
So the positive supply terminal is the middle pin of the three in a row, and the left most pin is the negative power supply pin, and the far right is the O/P pin.
The 'input' current then goes to the top row of pins, all pins, and the
'output' current goes to the middle row of 5 pins, all pins.
The output signal is taken from the pin at the far right (of the three pin row).
Note the input and output current above is just the current to be measured. The output signal itself is the O/P pin.
