Littelfuse TDR2A23 is an 8-pin plug-in time delay relay with a load rating of 10A resistive at 120/240V AC and 30V DC. It has a 1/3 hp rating at 230V AC. The time delay type is microcontroller, with a repeat accuracy of ±0.1% or 20ms, insulation resistance of ≥100, and power consumption of ≤2VA. It has a reset time of ≤150ms, a life of electrical: 1x10^5 and mechanical: 1x10^7 cycles, and a recycle time of ≤500ms. The undervoltage trip voltage can be set from 0 to 23s in 1s increments, with OFF adjustment set at 10-10V. The setting accuracy is ≤±2% or 50ms, and it has an input green LED for voltage indication and a relay red LED for relay energization indication.
