The setpoints may be configured for high or low settings, each with a high or low LED trip-point indicator. Input impedance is 100 ohms for current and 200 Kohms for voltage.
Model 9300 may be applied using both setpoints operating off Input A, or with individual setpoints operating off Input A and Input B. The changeover relays have a non-inductive rating of 5A at 250V AC or 30V DC.
The standard power supply is 95-265V AC/DC 50/60Hz, while 24V DC non-isolated supply is optional. The rail mount housing measures only 92 x 92 x 26mm wide, and is injection moulded from industrial strength flame retardant ABS.
