The latest real-time emulation hardware module from RF Solutions is designed to simplifythe development of embedded systems based on Arizona Microchip's PIC16F87X family of 8-bit microcontrollers
The system is remotely controlled via SMS messages sent to and from a GSM mobile phone.
The 250 has a wide and varied range of both domestic and industrial uses including applications such as remote alarm control, front door surveillance and remote gate opening.
Housed in an IP65 rated enclosure measuring just 145 x 90 x 45mm and with an operating temperature range of 0 to +55C, the 250 can be installed discreetly for use in both indoor and outdoor applications.
Supplied ready to operate, the unit only requires the connection of inputs, outputs and power supply, plus the installation of a SIM card.
When either of the two volt-free digital inputs is triggered, the 250 automatically sends a text message to a preconfigured telephone number.
The two relay outputs, each rated at 240V AC/12A, are also controlled via SMS text messaging.
In addition, system status can be requested at any time.
Connections to both inputs and outputs are made via simple screw terminals.
The 250 system requires a 12 or 24V DC power supply that can be connected via either a 3-pin terminal block or a jack socket.
A mains power supply unit is also available if required.
