A redundant power feed can also be added so power can be maintained in case one power supply fails. HART communications are also supported, allowing for data transfer from HART-compatible field devices. Increasing circuit load resistance, will reduce the supply voltage available to power the transmitter that is generating the 4-20mA signal. Status indication and alarm relays alert the control room of a failure for quick resolution. High power consumption compared to other analogue signal types. Common applications where MTL signal conditioning isolators are useful include elimination of grounding fault currents, signal conversion, noise reduction and signal repeat.Īvailable in a variety of configurations, the MTL 1000 signal conditioning isolators can accept many different inputs including 2/4-wire transmitters, Smart 2/4-wire transmitters, Type J and K thermocouples, PT100 Type RTD sensors, 3-wire potentiometers, switch/proximity detectors and voltage/current inputs. Analogue Inputs (high level) 2-wire transmitters, 4-20mA conventional and ‘smart’. Signal converter/insulator, Input : 2 x 0(4) - 20 mA, (loop powered), Output : 2 x 0(4) - 20 mA, Signal converter/isolator, dual channel, Input current loop. If additional guidance is required, contact your local representative. The optional power-bus feature reduces power wiring by up to 90% by providing power directly to the modules, making for quicker installation at a lower cost and the pre-fitted DIN rail power connectors allow for easy future expansion. For a given application the choice is between DIN-rail mounting (MTL5000/MTL5500 range) and backplane mounting (MTL4000/MTL4500 range) devices. MCR 3-way isolating amplifier, for electrical isolation of analog signals, with screw connection, input signal: 0(4) mA. MINI Analog signal conditioners isolate, convert, filter, and amplify your analog signals with a design width of just 6.2 mm. Galvanic isolation eliminates ground loops, reduces, noise, and blocks transient signals. On multi-channel units, each channel operates independently and is isolated from the others to prevent interaction between channels. The MTL 1000 signal conditioning isolators are easy to install and feature a slim-line design (6.2mm width) enabling high packing density. Isolator, Loop-Powered, Analog, Unconfigured Input, 4-20mA Output, Screw Conn. Signal isolators receive 4-20mA process current inputs and provide an isolated 4-20mA output signal.
