Version 2 - Parker 598P Applications Manual

Version 2

In version 2 the PCB has been re-tracked on a different software package and the components updated to
Standard Parts. This gives the following differences.
1) The PCB is slightly narrower (79mm) but fits on the same fixing centres;
2) Terminal Block A is split into two parts A1 to A4 and A5, A6 & Earth. This is to enable the use of the
Relay on AC Supplies up to 240 Vac where previously clearances were inadequate;
3) There is now an extra terminal between A6 7 Earth which is unused;
4) Radial Electrolytic Capacitors are used instead of Axial;
5) The add-on modification has been incorporated into the Circuit.
The functionality of the PCB is the same as before.
