The SP 8-100 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable. The SP 8-100 features a negative rail generator which enables the meter to measure a signal referenced to its own power supply 0V. The bright red LED display ensures excellent readability under low light conditions. The module is easily fitted into the panel, using the fixing clip provided. The module's low cost means it will suit high and low volume applications. The design of the panel meter's housing and seal ensures splash proofing in many applications.
The SP 8-100 module provides a 3½‑digit LED display with auto‑zero, auto‑polarity and programmable decimal points. It features a bright red LED, splash‑proof housing and a negative rail generator for measuring signals referenced to its own supply. The module is panel‑mountable using a fixing clip and is suited for both high‑ and low‑volume applications.
The datasheet lists dimensions, pin functions, circuit diagrams and scaling options, along with electrical specifications such as supply voltage, current consumption and temperature stability. Application notes describe voltage and current measurement modes and safety compliance with the Low Voltage Directive.
