Number of wire in cable varies depending on the number of contact used.
Wiring Procedure
(1) M4 screws are used for the terminals of the converter. Each cable should be terminated
corresponding to crimp-on terminals.
(2) The capacities of the contact output relay are 30 V DC 3 A, 250 V AC 3 A. Connect a load
(e.g. pilot lamp and annunciator) within these limits. AC and DC voltage cannot be mixed.
