Table5: Triac outputs names and specifications
£ Triac output connectors accept wires between 1 mm² (17 AWG) and 1.5 mm² (16 AWG). Make sure the cable performances suit
the connected loads.
£ To measure the state of a triac output, an external load must be connected.
£ It is not necessary to use a fuse when the onboard 24 Vac output is being used with the triac outputs since it already has built-in
short circuit protection (ECL-PTU-208 and ECL-PTU-308 only).
