The Series B4 is a 1/8 DIN digital differential pressure controller for positive, negative, and differential pressure as well as velocity and flow. The patented Series B4 Differential Pressure Cotnroller includes (2) 8A SPDT relays, and an optional digitally scaleable 4-20 mA and 0-5 V output. The programmable control allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done from a user friendly menu on the OLED display. The OLED also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate user preferences. The Series B4 is easily mounted in a 1/8 DIN cut-out with a panel depth of only 2.1 inches (53 mm).
