100% Original MTL3054 AND MTL3055 COMMUNICATIONS ISOLATORS/REPEATERS In Good Price Ready To Ship
MTL3054 AND MTL3055 COMMUNICATIONS ISOLATORS/REPEATERS.The MTL3054 and 3055 enable the extension of LONWORKS® into hazardous areas. The units provide power and communications via the signal conductor
The MTL3054 and 3055 enable the extension of LONWORKS® into hazardous areas. The units provide power and communications via the signal conductors. MTL3054: the number of devices that can be supported is a function of the power required by each device. MTL3055: two units may be used for communication across hazardous areas or for communication to LONWORKS nodes mounted in explosionproof (flameproof) enclosures in a hazardous area. Two MTL3055s may be used to give dual-redundant connection to a hazardous-area node.
SPECIFICATION OF MTL3054
See also 'Common specification'
Location of field devices (MTL3054)
Zone 0, IIC, T4–6 hazardous area if suitably certified
Location of field devices (MTL3055)
Zone 0, IIC, T4–6 hazardous area if suitably certified
Zone 0, IIC, T4–6 hazardous area if suitably certified when two
MTL3055s are connected together.
Hazardous-area power supply (MTL3054)
19.4V, 105Ω dc impedance typical
Maximum current 90mA
Hazardous-area power supply (MTL3055)
19.4V, 210Ω dc impedance typical
Maximum current 45mA
Hazardous-area maximum cable length
Determined by IS requirements depending upon devices attached
and maximum acceptable voltage drop along cable.
Free topology: 300m maximum (provisional value)
Bus topology: 1000m maximum
Hazardous-area digital signal transmission
78.1kbit/s, carried on same wires as power.
Signals are repeated between safe-area LONWORKS physical channel and IS physical channel.
Safe-area transceiver (MTL3054)
Similar to TP-78 devices with additional safety components required
by IS regulations. Operates with conventional TP-78 transceivers
but maximum number of nodes and maximum bus length are reduced.
Power requirement (MTL3054)
140mA typical at 24V with full load
110mA at 35V to 170mA at 20V with full load
Power requirement (MTL3055)
100mA typical at 24V with full load
90mA at 35V to 130mA at 20V with full load
Power dissipation within unit
2.5W typical at 24V with full load
2.8W maximum at 35V with full load
Replaceable fuse
250mA
Weight
170g
