(1) Removable Terminal Block.
(2) A fused common and blown fuse LED are provided on this module. See "Fuse Protection
and Blown Fuse Diagnostics" on page 32.
(3) Use ID Code 2803 when configuring your system with programming software or the HHT.
(4) Certified for Class 1, Division 2 hazardous location by CSA.
(5) Triac outputs turn on at any point in the ac line cycle, and turn off at ac line zero cross.
(6) To limit the effects of leakage current through solid state outputs, a loading resistor can
be connected in parallel with your load. For 120V ac operation, use a 15K Ω, 2W resistor.
For 240V ac operation, use a
15K Ω, 5W resistor.
