MTL5541 Intrinsically Safe Isolator relay 1–channel

The MTL5541 is a 1 Channel Isolation Barrier with Repeater Power Supply, 28 V max, 93mA max and it acts as a current sink for a safe-area connection rather than driving a current into the load. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication.

Description

MTL5541 Intrinsically Safe Isolator relay 1–channel

The MTL5541 is a 1 Channel Isolation Barrier with Repeater Power Supply, 28 V max, 93mA max and it acts as a current sink for a safe-area connection rather than driving a current into the load. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication.

Applications include the calibration of strain–gauge bridges; changing the polarity (and thereby the tone) of an IS sounder; the testing of IS fire alarms; and the transfer of safe-area signals into an annunciator with IS input terminals not segregated from each other. The output–relay contacts are certified as non–energy–storing apparatus, and can be connected to any IS circuit without further certification, provided that separate IS circuits are such that they would remain safe if connected together.

The MTL5500 (DIN-rail mounting) and MTL4500 (backplane mounting) isolators share a common design, differing only in the mechanical mounting and connection methods.

  • Compact modular design with DIN rail mounting
  • High packing density
  • Single and multi-channel I/O modules
  • 3-port isolation with low power dissipation
  • Compatible with MTL5000
