250 ms/4 points
Hexadecimal data (4-digit hexadecimal when normal display mode is selected or 8-digit hexa-
decimal when 1/100 display mode is selected.)
Between input and communication lines: Photocoupler isolation
Between temperature input signals: Photocoupler isolation
Note 1. A current of 0.35 mA flows to sensors connected to the DRT2-TS04P.
2. The indicator accuracy specifications differ depending on the mounting di-
rection. Refer to the above table for details.
In the DRT2-TS04T, a cold junction compensator is included in the Terminal
Block. The indicator accuracy will be reduced depending on the mounting
direction if just the Terminal Unit itself is replaced and the serial numbers of
the Terminal Block and Terminal Unit do not match. The serial numbers of the
Terminal Block and Terminal Unit can be found on the labels affixed to the
Units as shown below.
Terminal Unit Label
Remove the terminal block. The label is attached
to the Unit under the terminal block.
