4 SETUP AND PROCEDURES BEFORE OPERATION
(2) Q62AD-DGH
(a) For 2-wire transmitter input
(b) For current input
*1: Use a 2-core twisted shielded wire for the power wire.
*2: Shows input resistance.
*3: To connect with the 2-wire transmitter, be sure to connect to P and I/CHK+.
*4: Always use a ground. In addition, ground the FG of the power supply module.
*5: The check terminals (I/CHK+, CHK-) are used to check the amount of input in
mA in relation to the 2-wire transmitter output. This can be checked since
analog inputs of 4 to 20mA are converted to analog outputs of 1 to 5V. The
relationship of this conversion can be expressed by the following formula:
*6: Open the relay terminal surely because, the power supply for 2-wire
transmitter is always on.
