VDC, 3 amp each. Current Requirement: Relays de-energized - None
Relays energized - 45mA each
Actuation for each relay is from a high resistance
transistor input circuit, requiring a high going DC signal
from between 12 and 24 volts above system common. Ordering Information
Dual input actuation terminals are provided for each
relay to facilitate programming.
The model SR-30 is placement supervised, providing a
system trouble signal upon removal from the system.
