Multipoint Transmitters

The Adalet wireless multi-point systems utilise the hazardous area, NEMA or DIN rail transmitters (in any combination) and a receiver configured for base unit mode. The base unit can communicate with up to 60 transmitters. Output from the base unit is communicated with Modbus. Local outputs with 3 alarms, one discrete and one analogue output are also standard on the base units. The company can configure the complete system for quick installation. An interface programme for system configuration is also available.
Each multipoint transmitter can accept several process variable inputs including 4 to 20 mA, voltage, thermocouples, and RTDs as well as discrete On/Off (switch) inputs. RTDs and thermocouples are linearised to temperature. The transmitter is available with three power options: 1) 120/240 V AC 2) +24 V DC, and 3) battery power. The battery-powered device utilises two long-life rugged lithium batteries (up to four batteries in the explosion proof version). Battery life can be for several years under certain conditions. These devices utilise proven-reliable 900 MHz frequency hopping spread spectrum technology (FHSS). The output power can be adjusted to 1 watt, the maximum allowable by the FCC, to ensure data reception while achieving maximum transmission distance (miles in the case of line-of-site).
