ORDERING INFORMATION
• Code number: W2RS-[1][2][3]-[4][5]
Specify a code from below for each [1] through [5].
(e.g. W2RS-4A6-M2/BL/CE/Q)
[3] OUTPUT 2
Y: None
• Temperature range (e.g. 0 – 500°C)
• Special output ranges (For codes Z & 0)
• Specify the specification for option code /Q
(e.g. /C01/V01)

Z: Specify current (See OUTPUT SPECIFICATIONS)
Voltage
For the input code C, specify also the following. If not
specified, Cu 10 Ω @25°C (usable range -200 – +260°C) will
be used.
• Input type (e.g. Cu 10 Ω)
• Resistance range (e.g. 9.038 – 12.891 Ω)
Note: If one of the outputs should be a current range,
specify it for the Output 1 to allow a greater load.
Same range availability as Output 1
