The mark is crisp on one side of the workspace but becomes faint, out of focus, or entirely absent on the opposite edge.
The relay outputs on the EZD 361 are rated for electrical endurance of approximately 100,000 operations at full load (8A, 250V AC) and up to 10 million operations at low loads. For solenoid valves, motor starters, and indicator lamps, this lifespan is more than sufficient for a decade of normal operation. However, for high-frequency switching (e.g., PWM control), a transistor output variant is recommended. ezd 361
