Pulse Transmitter Connections
The CB-30 is designed to accept pulses from open collector transistors or dry contact closure transmitters
Before making any connections please make sure to comply with the following:
1 Always use shielded wire to protect the signal line from external noise (round shield to terminal #3)
2 Make sure the signal lines are not bundled with or touching power lines
