J1 Connector Signals
Pin
Signal Name
Description
1
PRL ON COM
Common for pin 16.
2
N.C.
Not connected.
3
N.C.
Not connected.
4
N.C.
Not connected.
5
ALM CLR
Alarm clear terminal
Alarms are cleared when a LOW (0 to 5 V) or short-circuit is applied
to this terminal.
6
SHUT DOWN
Output shutdown control terminal. The output is turned off when a
LOW (0 to 0.5 V) or short-circuit is applied to this terminal.
7
PRL IN-
Negative input terminal for master-slave parallel operation.
8
PRL IN+
Positive input terminal for master-slave parallel operation.
9
PRL COMP IN
Correction signal input terminal for master-slave parallel operation.
10
A COM
External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25.
During remote sensing, this is the negative electrode (-S) of sensing
input. When remote sensing is not being performed, this is connected
to the negative output.
11
PRL OUT+
Positive electrode output terminal for master-slave parallel operation.
12
PRL COMP OUT
Correction signal output terminal for master-slave parallel operation.
13
I SUM
Current signal terminal for master-slave parallel operation.
14
N.C
Not connected.
15
N.C.
Not connected.
16
PRL ON
On during master-slave parallel operation (output through an
open-collector photocoupler).
