Nominal Wattage is 0.35 @ 24 VDC
Maximum Allowable "Off" State Current to the Valves must be less than 1 mA.
Electronically Enhanced "IS" Solenoid:
Maximum Capacitor Charge Time — 1 second
Minimum Time between Cycles — 1 second
Minimum Drop Current to Reset Electronic Coil — 2 mA
Nominal Temperature Rise at 24 VDC and 300 Ohms — 2°C (36°F)
Maximum Recommended Wire Run (#18 Wire) — 1.5 miles from barrier to valve
Important: Minimum series resistance of 200 ohms required in wiring
circuit if a safety barrier is not used for non-"IS" system.
