GSM 4400 remote alarm monitors, supplied in Australia by Orbit Communications , have been designed to deliver convenient access to on-site resources and 24 hour remote monitoring of critical processes.
Housed in a heavy duty polycarbonate enclosure with a hinged door for easy access and padlock facility for security, these remote alarm monitors are rated IP65 water and dust-proof.
These units have four digital inputs for monitoring voltage-free contact sources, and four digital output that provide open collector switching.
DIN rail mounted 10A/240VAC changeover relays are an optional extra, and are supplied pre-fitted.
These remote alarm monitors also feature a built-in supply voltage monitoring circuit that can be used for monitoring power sources from renewable energy such as solar panels, and an auxiliary RS232 port.
Power conservation features include 5V DC regulated voltage outputs and switch supply voltage output, which allows remote sensors to be switched off when no readings are being taken.
GSM 4400 remote alarm monitors provide:
- convenient access to remote sites from the touch of a button
- alarm messages sent directly to a mobile phone
- UV stable construction
- wide operating temperature ranges of -20 to 70DegreesC); and
- 10V to 30V DC operation.
