LPRS multichannel telecommand transmitter and receiver modules

LPRS has released the CDT-TX-02M-R/CDT-RX-02M-R multichannel telecommand transmitter and receiver modules. The modules provide four selectable preprogrammed communication channels and six switch signal input/output processing circuits, allowing switch signals to be transmitted and received without the addition of external components.

The CDT-TX-02M-R and CDT-RX-02M-R modules provide long-range control, low-voltage operation with low current consumption for suitable battery operation and CDT-01-compatible communication format. Output switching is via PhotoMOS relays and all circuitry is housed in robust metal casings.

These CE-certified radio modules operate in the 434 MHz ISM band and feature: six switch inputs and outputs; transmitter standby mode in; four receiver operation modes; 10 mW RF output power; MSK modulation; receiver sensitivity -120 dBm; six switching signal transmission R&TTE (EN 300 220); and RoHS compliance. Power requirements for the CDT-TX-02M-R are 2.2-12 V at 27 mA with 1 µA at standby and for the CDT-RX-02M-R, 3.0-12V.
