Our 4MOD/4CPSI family of pulse loggers have been the backbone of literally hundreds of data acquisition system since 1999. They are simple, cost effective, and supremely reliable and this has ensured its appearance under a number of different brands in addition to our own. The latest addition to the family, the MOD-R is a radio linked version of its 'hardwired' sister. Handling up to 15 channels per device the MOD-R is a MODBUS connected radio receiver compatible with our standard RTCOM-P pulse transmitters. Available in both 434MHz UHF and 153MHz VHF formats it provides 'wirefree' reading of pulse output meters at distances of up to several kilometres, and links directly to an RS485 network or to an ethernet/intranet connection via our standard gateway. The units are extremely competitive, being priced at a similar level to the 'hardwire' 4MOD resulting in lower installed cost where cable runs are impractical.
