The company offers E-Series programmable process controllers in both 2- and 8-channel models. According to the company, model E-102 can accept and power two 4- to 20-mA signals, while model E-108 can read eight 4- to 20-mA signals, and both models can read two pulse inputs. The relay outputs can reportedly be assigned in any combination to either input channel and can be used for alarms, pump controls, and/or electric actuator controls. The controllers feature an override that allows switching between two process variables as the control input. The programmable relays can be set to vary the pulse width and time between pulses, according to the company. Other features include MODBUS RTU communications and displays in a range of engineering units such as ft, in, psi, and gpm. The controllers are designed for applications requiring digital readout for flow rates, monitoring of tank level, or temperature display, including throttle valves, pump switches, and security situations.
