The Phoenix MACX-TR-1T-POFF Timer Relay (Part No: 1119403) offers high-precision performance with an extended input voltage range of 24 V AC/DC to 240 V AC/DC (±15%) and a rated insulation voltage of 300 V AC. Built for stability, it delivers a mechanical service life of 3×10⁴ cycles and an electrical service life of up to 1×10⁵ cycles under 2000 VA resistive load. This Time Relay offers a wide timing range from 10 milliseconds to 10 minutes, with a fast recovery time of 250 ms—making it suitable for both short and moderate delay operations. It ensures reliable timing accuracy with a setting accuracy of ≤ 0.5% and a repeat accuracy of ≤ 0.05% for applications requiring repeated shutdown intervals. With a maximum switching voltage of 400 V AC, this relay supports demanding industrial systems. Installation is simplified through screw terminals supporting 0.2 mm² to 2.5 mm² rigid conductors, and the 8 A fast-blow output fuse provides built-in protection for connected equipment.
The MACX-TR-1T-POFF is a dependable choice for industries that need delayed power-off functions in systems like cooling fans, conveyor systems, packaging lines, and motor control circuits. It allows machinery to complete its process even after the control signal is removed, enhancing safety and operational precision. Engineers favor its compatibility with both AC and DC control logic, especially in panels where post-power shutdown timing is critical. With an ambient operating temperature range of -25°C to +60°C, the device withstands tough Indian industrial environments. Maintenance professionals appreciate the secure screw connections and the standardized 10 mm stripping length for efficient panel assembly. This model also serves as a training asset for students learning automation logic involving power-off delays and relay configurations in real-world settings.
