• Accepts two DC inputs and provides two isolated standard process signals proportional to the difference of the two signals
• Isolation up to 2000 V AC
• High-density mounting (1.97) 132 (5.20) (3.15) mm (inch) K-UNIT MODEL: KWSBS–[1][2][3]–[4][5]

ORDERING INFORMATION

• Code number: KWSBS-[1][2][3]-[4][5] Specify a code from below for each of [1] through [5]. (e.g. KWSBS-6A6-B/Q)
• Special input and output ranges (For codes Z & 0)
• Parameters (e.g. K1 = 2.00, K2 = 0.10)
• 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.
