ORDERING INFORMATION

• Code number: WRS-[1][2][3]-[4][5] Specify a code from below for each of [1] through [5]. (e.g. WRS-4AA-B/E/BL/Q)
• Temperature ranges (e.g. 0 – 500°C)
• Special output ranges (For codes Z & 0)
• Specify the specification for option code /Q (e.g. /C01/S01) Note: When the user requires a current and a voltage output, specify the current to be the Output 1 which allows a greater load.
