Page 6: Input Types
Input types Utility meters generate output pulses with type C contact, known as pulses, where each contact is a pulse. DH96-CPP uses type two wires contact, this can be obtained from type using either only. AC o DC Pulse generator... - Page 7 Input types For it, the DH96-CPP will count a pulse whenever the position of the contact should be modified, it's means, in every change of level. DH96-CPP admits, for each of his two inputs - synchronism input pulses - the connection through:...
