The EX1200-7600 is a 5W Programmable Resistor Ladder, ideal for UUT loading or simulation.
The EX1200-7600 is a single output, programmable resistor ladder. It is designed for applications such as RTD or other sensor simulation, process control, ATE calibration, and device under test loading. It contains internal, high-precision 5 W power resistors that are switched in and out via mechanical relays. The EX1200-7600 is capable of producing any resistance value between 0.5 Ω to 1,500,000 Ω and can be adjusted in 0.1 Ω increments via external commands. It is designed for terminal voltages from 0 to 200 V DC and for currents up to 0.5 A.
FAULT SENSING
After power up, reset or a fault condition, all relays on this module are open, removing the load from the device under test. A fault condition is the result of exceeding the maximum current, maximum voltage, or maximum temperature for the module. Additionally, a voltage sense out signal provides a scaled indication of the voltage across the resistance, and a current sense out signal provides a scaled indication of the current through the circuit. Both of these can be monitored by an external measurement device (such as an EX1200 series DMM). This can be used to force all relays open if a set voltage or current is exceeded thereby protecting the unit under test.
