Discontinued Thermocouple Input Three-wire Transmitter Q424 and Q425
Provides 2 DC outputs in proportion to 2 thermocouple (mV) inputs Multi-channel design provides 2 three-wire transmitters in a single package Protects equipment and eliminates ground loops with 1800VDC isolation Output linear to mV input Felxible supply voltage from 18 to 30VDC High density DIN rail mounting LED indicators SnapLoc™ plug-in terminals for low MTTR Three year warranty Datasheet
The ActionI/Q models Q424 and Q425 are DIN rail mount, thermocouple input, dual-channel, three-wire transmitters. Each channel accepts a millivolt input and provides a DC output signal linear to input temperature. Three-wire transmitters are primarily used in remote locations, near field sensors, since they reduce signal errors and require less wiring by utilizing one of the two power wires as a common reference, sending either a 4 to 20mA (Q424) or 0 to 10VDC (Q425) signal to a control system. The Q424 and Q425 are CSA and UL certified, and CE Mark compliant.
