PIN Inputs |
|
Maximum input voltage range | 0V to +24V |
|
|
Input ‘low’ threshold | < 2V |
|
|
Input ‘high’ threshold | > 3V |
|
|
Input | Internal 10K to 5V supply |
|
|
Relay Outputs |
|
Maximum operating voltage | 24V |
|
|
Maximum current rating | 1A |
|
|
Power Supply |
|
Supply voltage | 9 - 30V DC |
|
|
Ethernet only (typical current) dialer on hook | 145mA (supply at 12v) |
|
|
Ethernet only (typical current) dialer off hook | 175mA (supply ay 12V) |
|
|
With GSM/GPRS (typical current) dialer on hook | 185mA (supply at 12V) |
|
|
With GSM/GPRS (typical current) dialer off hook | 215mA (supply at 12V) |
|
|
Note: These figures are based upon the Ethernet link being connected. With GSM/GPRS there will also be additional transient peak current of up to 250mA required as GSM and GPRS transmissions (e.g. for network registration and calls) are made.
