Model SP-35X Signal Powered DC Volt Digital Meter

The SP-35X is a signal powered meter designed for ease-ofuse. The 2 wire meter is powered from the signal, and does not require a separate power supply. This meter has Auto-Polarity indication. The polarity indication may be disabled or reversed by repositioning jumper clips on internal header pins.
Each SP-Series meter is provided with a set of screw terminal blocks that can accept either bare wire or crimp-on 0.110" x 0.032" insulated disconnects. The SP-Series pin out is designed so that a standard PCB edge connector can also be used instead of the screw terminal blocks if desired.
