Description

The FMT154… has a transmission power of 1000mWatt. It gives a controlled range of up to 5km. The controlled

operation can be any electronic or electrical operated device when used with the FMR154… series of receivers

The channels are activated via screw type terminals onto which the user can connect reed switches, toggle

switches, push buttons or any form of normally open (NO) contact.

The transmitter uses a frequency of 154MHz and a modulation type of Narrow Band Width FM which makes it

suitable for industrial applications where you would have a high level of electrical interference. This transmitter is

not affected by man made or electrical interference. This makes FMT154... an ideal choice for use in heavy

industrial environment.

Each transmitter button is individually transmitted to the receiver making it possible to do simultaneous channel

transmission. This means that up to 8 different functions can be done at the same time. Each button can operate

any FMR154… series receivers making it possible to transmit each button to different single channel receivers or

to multi channel receivers

The transmitter uses a specially programmed micro-controller which ensures the highest reliability, low standby

current consumption (10uA) and greater flexibility. The greater flexibility allows customers to contact us and

request custom written software for special functions.

External supply connection and SO239 antenna socket is provided with the transmitter.
