Cebek DTMF-2 is a Dual-Tone Multi-Frequency (DTMF) 4-channel receiver module with mains rated relay outputs.
It allows you to remotely control the relay outputs using a DTMF transmitter like the DTMF-1. It decodes DTMF tones 0 to 9, * and #.
The relay outputs can be configured to operate in Momentary, Latching or Timer mode.
It includes password or access code functions.
NB This is NOT the same as a Telephone Activated Relay Board. It cannot be directly connected to the phone system.
