DO8 - digital output - 8 channel
The DO8 provides higher packing density and lower cost per channel. The eight digital output module provides eight logic outputs, which are typically used for control, alarms or events outputs. Each channel a 24V output with 0.75A capability (subject of a maximum of 4A total per module) can be used for driving solenoids, relays, lamps, fans, thyristor units, single phase Solid State Relays (SSRs) or some three phase SSRs.
Voltage supply (external): 18-30V dc to plant devices Vs
RLY4 - relay output - 4 channel
This digital output module provides four relay outputs. The relay contacts are all fitted with removable snubber circuits to reduce contact arcing and prolong contact life.
No of channels: 4 (3 normally open + 1 changeover)
Max current rating: 2A at up to 240V ac; 0.5A at 200V dc,
ncreasing to 2A at 50V dc (resistive)
