Relay Module Wiring
3-9950.393-1 and 3-9950.393-2
Relay 1: The alarm is OFF during normal operation, and will
go ON when relay energizes according to 9950
Relay settings.
Relay 4: The valve is ON during normal operation, and will
go OFF when relay energizes according to 9950
Relay settings.
NO = normally open (closes when energized)
NC = normally closed (opens when energized)
Mechanical Relays Rating:
5A 250 VAC, 5A 30 VDC
Solid State Relays Rating:
50 mA 30V AC/DC
(for 309950.393-2 relay 1 & 2)
3-9950.393-3
The alarm is OFF during normal operation, and will go ON when the
relay energizes according to 9950 Relay settings.
Binary input 4 will be ON when the tank level is above the level
switch, Binary Input 4 will be OFF when the tank level is below the
level switch.

•
Terminals accept 12 to 22 AWG wire.
•
Strip 10 to 12 mm (0.4 to 0.5 in.) of insulation from wire tips and tin bare ends to eliminate fraying.
•
Insert wire tip or ferrule completely into the terminal and secure with the screw.
•
Do not allow any AC leads that may be connected to the internal relays to come in contact with low voltage wiring.

3-9950.393-3 Internal Power
3-9950.393-3 External Power
If an externally powered sensor is connected with the
3-9950.393-3 module, set the power switch to the EXT
position. The module can power external sensors by
switching the power switch to the INT position. Maximum
power that can be drawn from the module is 6mA at 30 VDC.
