|
How installed |
Installed in the I/O Module Nest. |
|
How connected |
Connected to the terminals of the I/O Module Nest with M4 screws. |
|
How input signals are specified |
Specify input signals and range by software setting. |
|
*1: This module can be combined with MTL barrier 728. At this time, wiring resistance must be 10 Ω or less and the lowest operating voltage of the 2-wire transmitter must be 12 V DC or less.
*2: When the power of AAM10 is OFF or an abnormal condition occurs, the current input loop is open.
Do not share current signals with other receivers. To share signal, attach Shunt Resistance (250 Ω) to current-output module and share voltage output.
