Hi, The requirements for insulation between the Applied Part, F-type and the Signal Input part is defined in clause 20.2, part B-d. You need Basic insulation. The working voltage is at a minimum the rated supply voltage. See clause 20.3, paragraph 6. So, assuming 230 Vac input. The requirements are Basic Insulation, Dielectric is 1,500 Vac. Creepage is 4.0 mm, Air Clearance is 2.5 mm. You can use anything the meets these requirements. See also Clause 17.a) for separation requirements. Ned

The signal input is connected to the parallel port of a computer. I understand that the insulation has to be a supplementary one. Does this mean that I need to have a galvanic insulation (with optocoupleur, for example) or can I use another system ? Thanks a lot for your contribution. Bonnes fêtes de fin d'année et meilleurs voeux pour 2002 (happy new year and best whishes !) ======================================== eLABs Pierre SELVA 18 Rue Marceau Leyssieux 38400 SAINT MARTIN D'HERES - FRANCE Phone : 33 (0)6 76 63 02 58 Fax : 33 (0)6 61 37 87 48 e-mail : e.l...@wanadoo.fr <mailto:e.l...@wanadoo.fr> ps.el...@laposte.net <mailto:ps.el...@laposte.net> ======================================
