FNIRSI SG-002 4-20mA Signal Generator with Battery – 0-24mA Current and Voltage Source
The FNIRSI SG-002 is a low-cost current and voltage signal source for testing PLC analog inputs, valve actuators, VFD speed inputs and panel meters. It outputs 0 – 24mA in 0.01mA steps, covering both 0 – 20mA and 4 – 20mA standards, in active or passive loop configuration.
Switch to voltage mode for 0 – 10V style signals. It runs from its internal lithium battery, from USB 5V, or from a 15 – 30V external supply such as a PLC's 24V rail, and connects through detachable screw terminals.
