Relay outputs
Most of the ArcGlide THC outputs are relay contacts and can be used for either AC or DC loads. All relay outputs are
protected with thermal fuses that automatically reset and protect against currents above 100 mA. The 24 V supply is
limited to a total of 2 A for all outputs.
Figure 31 shows a simplified schematic of the ArcGlide THC outputs.
