SP 200产品概述
The SP Series consists of five 31⁄2-digit voltmeters with ±200 mVDC full scale reading, a 3-digit 2-wire signal powered voltmeter (SP 5-1200-BL) and a 17 segment, analog-style LCD panel meter (SP 5-1710-BL). The SP Series voltmeters are available in LCD and LED format with 12-pin modules allowing more modes of operation and compatibility with similar competing modules. 9-pin versions are lower cost, easier to use and more suited to new designs. All modules when fitted with the rubber seal supplied are splashproof protected from the front.
