Overview

The Honeywell MTL4599N feed-through module offers a simple and reliable way to route unused or non-IS signals through MTL4500 and MTL5500 backplanes. Each module provides clean termination points for spare conductors, ensuring tidy wiring and improved system integrity. Moreover, its compact design supports fast installation on both DIN rails and dedicated backplanes. The module fits naturally into modern instrumentation panels, as many engineers rely on it to maintain safe separation between IS and non-IS circuits.

FAQ

Q1: Can the MTL4599N be used for hazardous-area IS signals?
No. It passes signals directly and should not be used for intrinsically safe circuits requiring certified isolation.

Q2: Does the module provide surge or transient protection?
No. External protective devices should be used if surge suppression is required.

Q3: Can I route analog and digital signals through the same module?
Yes, although proper wiring discipline is recommended to avoid interference.

Q4: Does the unit require a power supply?
Only optional indicator functions may need 24 VDC; basic feed-through operation requires no power.

Q5: Is the MTL4599N backward-compatible with older MTL baseplates?
Yes, it fits standard MTL4500 and MTL5500 backplane connectors.
