MTL7207+ safety barrier for digital (switch) inputs
SPECIFICATION
Supply voltage, terminal 1
+10 to +35V dc
Normal operation
In normal operation the protection circuit introduces only a small
voltage drop and shunts less than 1.5mA to earth, so its overall
effect is minimal
Supply voltage >27V
If the supply voltage exceeds about 27V, causing the Zener
diodes to conduct, or if the safe-area load has a very low
resistance, the supply current is limited automatically to <50mA.
This protects the fuse and power supply and enables the loop to
continue working.
Supply current
At Vs <26V; Iout + 1.5mA max
At Vs >28V or low load resistance; limited to <50mA
Internal fuse, terminal 1
50mA
Reverse voltage protection, terminal 1
Yes
Maximum voltage drop, terminals 1 to 4
[(Iout x 350Ω) + 1.2]V (current not limited)
Output current (Iout), terminal 4
Up to 35mA
Leakage to earth
1.5mA max
