RT28U On-Off Temperature Controller with Universal Analog Input 12-24VAC
Panel mount programmable on-off controller for RTD, PTC, NTC, thermocouples, voltage or current temperature sensors. Two changeover relay outputs. 12-24 VAC/DC powered.
The RT28U is a programmable thermostat controller with a universal analog input that accepts a wide range of sensor types and two independent relay outputs. Although primarily designed for temperature control it can be used for ON-OFF control of level, pressure etc.
Each relay has independent settings for setpoint, hysteresis, cooling or heating action and on time. Each output can be set to a pulse mode where the relay constantly toggles on and off when the temperature exceeds (or falls below) the setpoint.
The controller has peak filtering and low pass filtering options. The display or linear input signals can be scaled to any value between -199 and 999 with a configurable decimal point.
