The IFD 258 automatic burner control unit can be used to control gas burners and may work for UV control settings and a cut-off rate for a flame current. This also uses measuring sockets for a flare current measurement, a single-electrode option, signal contacts for operating needs and an EC type tested unit. This can take up to ten seconds for start-up and can use 1 second safety time in operation. This also works at 100, 115, 200 or 230 V AC for any earthed or unearthed main.
