1CH-4xx-HTLP FM Receiver Module Low Power Platform

The 1CH-418/433-HTLP is a low power radio receiver platform designed to accommodate the SILRX range of

receiver modules and to operate in conjunction with a transmitter design employing the TXM series FM trans-

mitter module, together with the Holtek HT-12-E encoder IC. The unit has been specifically designed to oper-

ate at very low current levels, permitting its retro-fit to any system without the need for increased power sup-

ply capacity. Alternatively the receiver may be operated for considerable periods from batteries.

Three versions are available providing operation from 9, 12 or 24V dc supplies. High voltage operation from

supplies above 24V is also possible as the receivers low current consumption permits excess voltage to be

simply dropped using a series connected Zener diodes. The alarm output is fully isolated via a 125Vac 0.5A

output relay with normally open contact.

The receiver platform is supplied in compact PCB format, with both power and alarm LED's. Received data is

decoded using the Holtek HT-12-D. Address bits A0 to A3 are switch programmable and bits A4-A7 may be

drill programmed to give the full 256 code combinations.

Applications include nurse call systems, panic attack alarms, lone worker systems and remote control sys-

tems.
