9 / 64 page ![]() E5CZ/E5CZ-U 9 Current Transformer (Order Separately) Ratings Heater Burnout and Heater Short Alarms Note: 1. If the ON time of control output 1 is less than 190 ms, heater burnout and the heater current will not be measured. 2. If the OFF time of control output 1 is less than 190 ms, heater short alarm and the heater current will not be measured. Electrical Life Expectancy Curve for Relays (Reference Values) E54-CT1 Thru-current (Io) vs. Output Voltage (Eo) (Reference Values) Maximum continuous heater current: 50 A (50/60 Hz) Number of windings: 400±2 Winding resistance: 18±2 Ω E54-CT3 Thru-current (Io) vs. Output Voltage (Eo) (Reference Values) Maximum continuous heater current: 120 A (50/60 Hz) (Maximum continuous heater current for an OMRON Temperature Controller is 50 A.) Number of windings: 400±2 Winding resistance: 8±0.8 Ω Dielectric strength 1,000 VAC for 1 min Vibration resistance 50 Hz, 98 m/s2 Weight E54-CT1: Approx. 11.5 g, E54-CT3: Approx. 50 g Accessories (E54-CT3 only) Armatures (2) Plugs (2) Maximum heater current 50 A AC Input current indication accuracy ±5% FS ±1 digit max. Heater burn- out alarm set- ting range 0.1 to 49.9 A (in units of 0.1 A) 0.0 A: Heater burnout/Heater short alarm output turns OFF. 50.0 A: Heater burnout/Heater short alarm output turns ON. Minimum detection ON time: 190 ms (See note 1.) Heater short alarm setting range 0.1 to 49.9 A (in units of 0.1 A) 0.0 A: Heater burnout/Heater short alarm output turns ON. 50.0 A: Heater burnout/Heater short alarm output turns OFF.
