CTA28 : CTA88 chip based 2 channel application boards

CTA28 - CTA88 chip based 2 channel application boards

The CTA88 chip is a simple encoder/decoder for use with ISM band telemetry modules. It permits a simple, one way wireless link to be established, for simple remote control applications, with a minimum of effort and no customer software input.
These tx and rx application boards are designed to allow easy evaluation of the CTA88 device in elementary jobs. They provide simple 2 channel implementations, using either LMT/LMR or BiM footprint radio modules.

Features

• 8 bit address and 2 bit data select switches
• 2 relays to control mains powered devices rated up to 8A, 250VAC/30VDC
• Visual indication of valid code received and active relays
• RF module range testing
• Push button for momentary control of relays
• Momentary, Latched outputs
• Dynamic relay state changes
• Setup is simple as Plug-and-Play
• RF Remote Control Demonstration

Applications

• Wireless Security and Alarm systems
• Emergency assistance call system
• Status reporting and monitoring systems
• RF Remote control systems
• Industrial controls
• HVAC controls
• Simple On/Off switching
• Long range telecontrol with narrow band FM radios
