EATON - MTL4521L, MTL4549Y, MTL5546, MTL5510, MTL4510 Intrinsically Safe Isolators. Isolates hazardous and safe area circuits. Simplifies installation and avoids earth-loop problems. The MTL4500 range is the latest generation of backplane mounting products, building upon the heritage of MTL4000 and introducing many key application benefits. The MTL5500 range launches a new industry standard for DIN rail mounting products, ideally suited to a wide variety of interface tasks for process instrumentation.

MTL4521L loop powered solenoid driver IIC

The MTL4521 and the MTL4521L are loop-powered modules which enable a device located in the hazardous area to be controlled from the safe area. They can all drive a certified intrinsically safe low-power load, as well as non-energy-storing simple apparatus such as an LED.

MTL4549Y 2ch 4-20mA smart isolating driver + oc LFD

The MTL4549 accepts 4/20mA floating signals from safe-area controllers to drive 2 current/pressure converters (or any other load up to 800Ω) in a hazardous area. For HART valve positioners, the module also permits bi-directional transmission of digital communication signals. Process controllers with a readback facility can detect open or short circuits in the field wiring: if these occur, the current taken into the terminals drops to a preset level. The MTL4549C and MTL4549Y are very similar to the MTL4549 except that they provide open circuit detection only (i.e. no short-circuit detection).

MTL4510 4ch DI solid-state output

The MTL4510 enables four solid-state outputs in the safe area to be controlled by up to four switches or proximity detectors located in a hazardous area. Each pair of output transistors shares a common terminal and can switch +ve or –ve polarity signals. A range of module configurations is available through the use of selector switches. When proximity detector modes are selected, LFD is enabled and the output switches to OFF if a line fault is detected.

MTL5546 1ch 4-20mA smart isolating driver + LFD

The MTL5546 accepts a 4/20mA floating signal from a safe-area controller to drive a current/pressure converter (or any other load up to 800Ω) in a hazardous area. For HART valve positioners, the module also permits bi-directional transmission of digital communication signals. Process controllers with a readback facility can detect open or short circuits in the field wiring: if these occur, the current taken into the terminals drops to a preset level. The MTL4546C and the MTL5546Y are very similar to the MTL5546 except that they provide open circuit detection only (i.e. no short-circuit detection).

MTL5510 4ch DI solid-state ouput

The MTL5510 enables four solid-state outputs in the safe area to be controlled by up to four switches or proximity detectors located in a hazardous area. Each pair of output transistors shares a common terminal and can switch +ve or –ve polarity signals. A range of module configurations is available through the use of selector switches. When proximity detector modes are selected, LFD is enabled and the output switches to OFF if a line fault is detected.
