CHAPTER 2 INSTALLATION AND CONNECTION
Input
2-6
Input signals to be measured.
Input that can be measured by each model is as follows:
Voltage/Current (K3MA-J)
According to the input type, connect input devices to terminals shown below.
Be sure not to exceed the absolute maximum rating even for a moment.
(+)
( - )
Temperature (K3MA-L)
According to the input type, connect input devices to the terminals E4-E6.
Pulse signals (K3MA-F)
According to the types of signals to be input, connect input devices as shown below.
For the PNP sensor input connection, refer to "1-3 I/O Circuit".
The input equipment connected to these terminals must meet the following
conditions.
Transistor: ON residual voltage:
OFF leakage current:
Current leakage with Transistor turned ON: 15 mA min.
Relay: Min. load current:
Voltage pulse:H Level:
L Level:
