GF+SIGNET 8860系列双路电导率控制器详细英文介绍
8860 Dual Channel Conductivity-Resistivity Controller
The Signet 8860 Dual Channel Conductivity/Resistivity Controller is a two-channel input device equipped with three scaleable 4 to 20 mA outputs and four programmable relays. A selector switch activates two open collector outputs in place of two of the relays for extraordinary output versatility. Dual input and advanced control capability, including percent rejection, difference and ratio calculations, together with Signet Conductivity Sensors, form the perfect measurement and control system for water treatment applications and more. Two versions are available: once accepts AC line-voltage, the other low voltage DC for power. The four-button keypad arrangement with intuitive software design is user-friendly, and the NEMA 4X/IP65 front panel with self-healing window in a 1/4 DIN package for easy panel installation.
