RFM HNIO modems feature bidirectional transmission
and the company’s patented FHSS technology. The product
line includes the HNIO-091R and HNIO-241R relay
modems, which operate at 900 MHz and 2.4 GHz
respectively, and two analog/digital modems, the 900 MHz
HNIO-091A and 2.4 GHz HNIO-241A. The relay modems
provide four 250VAC 5A relays, and the analog/digital
modems provide two 4-20mA receivers and transmitters
along with two digital I/O channels.
Unlike wireless data transceivers, which transmit serial
data streams, wireless I/O modems transmit voltage or

HNIO Cables, Antennas, and Accessories
RFM offers a full line of cable, antennas and accessories for use with the HNIO family of products. See the
RFM CD catalog or go to www.RFM.com for detailed listings of accessories.
MHz I/O modems and up to seven miles for the 2.4 GHz
units, depending upon the antenna used. The modems can
operate over an input voltage range of +9Vdc to +30Vdc,
making them suitable for battery and solar power sources.
Class I Div 2 certification allows the modems to be
deployed in hazardous locations. All are DIN-rail
mountable.
