Standard control output signal is 2 to 10 V dc or 4 to 20 mA with a 500-ohm resistor. Feedback signal is 2 to 10 V dc. Mass. More than 300 noncontact infrared temperature sensors are available. They have reportedly been produced according to NEMA specifications, including NEMA 4 and 4x. They are made to be intrinsically safe.
Universal inputs are scalable and can be programmed for thermocouples, RTDs, or voltage.
The UT2000 series interfaces to a touch screen MMI, a small multiline display, PLCs, or a supervisory computer system. UT2000 accepts thermocouples, RTDs, or DCV signal and executes control through the universal output system. Other features include a standard RS422A interface, universal power, up to eight sets of setpoints and control parameters per control channel, and optional heater break alarms. N.J. Three-way, pneumatically actuated, ball valves have been added to this company's True Blue line. All models include manual override capability.
