VARIANTS Variant features of the ESX.iot The variants listed here are STW standard variants. Further variants available on request. A complete overview of the possible assignment of each individual pin can be found in the PIN ASSIGNMENT . preferred ESX.iot X_OUT_OPHB4A_4CT (with current measurement) IO) X_OUT_OPHB4A_4CT_NCM (without current measurement) Outputs can be initialized as IDTA35V_4CT inputs. This invokes risks an restrictions due to possible reverse supply of other outputs over the freewheeling diode inside the switch. Subject to change without notice
