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
