Digital Output Relay Modules Low Voltage DO Relay Modules: The DO Relay modules have 8 or 16 outputs. There are two types of DO relays: ƒ Electrically Energized (EE) - the outputs return to the non-energized state in case of power off or module failure. ƒ Magnetic Latch (ML) - Relay outputs are magnetically latched, the outputs maintain their state in case of power off or module failure. The following DO relays modules are available: ƒ 8 DO EE Relay 2A ƒ 16 DO EE Relay 2A ƒ 8 DO ML Relay 2A ƒ 16 DO ML Relay 2A In the 8 DO modules, the relays of outputs 1 through 5 are Single Pole Single Throw (SPST) normally open (NO) and are referred to as the "Form A" relays. The relays of outputs 6 through 8 are Single Pole Double Throw (SPDT) and are referred to as the "Form C" relays. In the 16 DO modules, the relays of outputs 1 through 5 and 9 through 13 are Single Pole Single Throw (SPST) normally open (NO) "Form A" relays. The relays of outputs 6 through 8 and 14 through 16 are Single Pole Double Throw (SPDT) "Form C" relays. 120/230V DO Relay Modules: The ACE3600 DO Relay 120/230V (High Voltage DO) modules have 12 outputs. Each output is switched by a relay. There are two types of DO relays: ƒ Electrically Energized (EE) - the outputs return to the non-energized state in case of power off or module failure. ƒ Magnetically Latched (ML) - Relay outputs are magnetically latched, the outputs maintain their state in case of power off or module failure. The following DO relays modules are available: ƒ 12 DO EE Relay 120/230V 3A ƒ 12 DO ML Relay 120/230V 3A DO Modules Common Characteristics: The physical position of each relay is monitored by the module logic, using a back indication signal which is connected to the relay's second contact set.

Digital Output Relay Modules
Low Voltage DO Relay Modules:
The DO Relay modules have 8 or 16 outputs. There are two types of DO relays:
±
Electrically Energized (EE) - the outputs return to the non-energized state in case
of power off or module failure.
±
Magnetic Latch (ML) - Relay outputs are magnetically latched, the outputs
maintain their state in case of power off or module failure.
The following DO relays modules are available:
±
8 DO EE Relay 2A
±
16 DO EE Relay 2A
±
8 DO ML Relay 2A
±
16 DO ML Relay 2A
In the 8 DO modules, the relays of outputs 1 through 5 are Single Pole Single Throw
(SPST) normally open (NO) and are referred to as the “Form A” relays. The relays of
outputs 6 through 8 are Single Pole Double Throw (SPDT) and are referred to as the
“Form C” relays.
In the 16 DO modules, the relays of outputs 1 through 5 and 9 through 13 are Single Pole
Single Throw (SPST) normally open (NO) “Form A” relays. The relays of outputs 6
through 8 and 14 through 16 are Single Pole Double Throw (SPDT) “Form C” relays.
120/230V DO Relay Modules:
The ACE3600 DO Relay 120/230V (High Voltage DO) modules have 12 outputs. Each
output is switched by a relay.
There are two types of DO relays:
±
Electrically Energized (EE) - the outputs return to the non-energized state in case
of power off or module failure.
±
Magnetically Latched (ML) - Relay outputs are magnetically latched, the outputs
maintain their state in case of power off or module failure.
The following DO relays modules are available:
±
12 DO EE Relay 120/230V 3A
±
12 DO ML Relay 120/230V 3A
DO Modules Common Characteristics:
The physical position of each relay is monitored by the module logic, using a back
indication signal which is connected to the relay’s second contact set. Any contradiction
