POWERING OMEGA
Battery Power Supply
The Omega controller is powered by four LR-14
(C-size) alkaline batteries (see battery datasheet in full manual)
NOTE: In offline mode, the controller can run on battery power for up to five years
Tip: For best performance in outdoor installation, use batteries with an operating temperature range of
-18° to 55° C or greater
CAUTION : Running the Omega controller on battery power in online mode shortens battery life significantly
In sert four batteries according to the orientation shown in the battery compartment
20 21
External Power Source
The Omega controller can be powered by electrical grid power, external high-capacity batteries, or solar panels
22
NOTE: An external power supply is necessary if operating the Omega controller in online mode for an extended amount of time
CAUTION :
• Connect the power cable to the Omega power connectors before turning on the power source
• The Omega controller must first be unplugged from the external power source before disconnecting the power supply cables from the power connectors
Ve rify the power supply provides 9-24 VDC/1 A
Verify the external power source polarity matches the polarity marked on the connector board
23
CONNECTING PERIPHERALS
Latch Output Connections
Up to five devices (such as valves and water pumps) can be connected to the Omega controller latch outputs
24
NOTE: The Omega RS model features up to four latch outputs and one RS-485
MODBUS
Latch solenoid valve
1 2 3
4 5
Activated via 25 ms pulses
Latch relay
Pump
A relay must be connected between the latch output and the pump
25
Digital Input Connections
Up to four devices (such as water meters and digital sensors) can be connected to the Omega controller digital inputs.
26
NOTE: Digital inputs can be connected to devices with one of the following outputs:
- Dry contact
- Open collector
CAUTION : Ensure the open collector connects according to the input polarity marked on the connector board .

27
Analog Input Connections
Up to two devices (such as the following types of analog sensors) can be connected to the Omega controller analog inputs.
Two-wire active analog sensor (connected to an external power source)
Three-wire passive analog sensor (powered by the Omega controller)
28
NOTE: The controller supports both analog voltage (0-10 V) and analog current (4-20 mA) sensor
CAUTION : Ensure setting the correct analog protocol before connecting the sensor
