Intrinsic safety variants offer yet more options

Intrinsic safety and isolation from MTL has expanded. Top of the bill are a daisy chain power bus for its 5000 galvanic isolators, a 4-20mA isolating driver with smarts, and new 7000 range shunt diode safety barriers. The power bus reduces wiring and saves time; four variants can power up to 32 MTL 5000 modules […]

Intrinsic safety and isolation from MTL has expanded. Top of the bill are a daisy chain power bus for its 5000 galvanic isolators, a 4-20mA isolating driver with smarts, and new 7000 range shunt diode safety barriers.

The power bus reduces wiring and saves time; four variants can power up to 32 MTL 5000 modules from a standard 24V supply. Then MTL 5046 permits bidirectional digital comms on 4-20mA signals from a controller in a safe area.

On MTL 7000, there’s two new overvolt-protected link-disconnect barriers, two higher power devices and a single channel version with earth return for 18V d.c. Then, on the 4000 backplane devices, there’s a new high level 4-20mA trip amp – the 4403.
