Extensive protection against field and mains power surges
Relay outputs to field valves ensures reliable operation under the most severe conditions.
Normal Time 1. Time and day 2. Next program and start time. 3. Rain Switch displayed, or power fail signal.
|Input power||240 volt 50 Hz Single phase or 12 volt DC|
|Operating limits||210 VAC to 265 VAC or 11 VDC to 16 VDC|
|Quiescent 12V input power||15 mA at 12VDC (55 mA with one output relay and pump start relay active), total current = solenoid current + 70mA|
|Output power||Total station capacity, 24 VAC at 2.0 A max. or 12 VDC at 2.0 A max|
|Superior lightning and surge protection||Transformer primary, 275V, 2,500 amp/20 micro sec. Surge protection, A-E, N, E. Transformer secondary, 24 VAC, 6,500 amp/20 micro sec. Field wiring (32 stations and pump start), 6,500 amp/20 micro sec. Large valve wiring terminals, detachable, do not need to remove valve wires for servicing Permanent program memory maintains all saved programs if power fails. No standby battery is required 9 volt Alkaline battery keeps correct time during power failure. (150 hours nominal) Relay outputs to field valves ensure reliable operation in the most rugged conditions Operating Conditions|
|Temperature||-10°C to 65°C|
The breakthrough result of more than 30 years of tape research, development and manufacturing.
