TS125L-Ex-1-00, Isolating Switch Amplifier with Intrinsically Safe Inputs
This isolating switch amplifier is used in control cabinets for converting and separating digital switching signals, including those from areas where there is a risk of explosion.
Passive encoders such as e.g. switching contacts, Namur initiators or passive electronic outputs from third-party devices can be connected.
The TS125L in the 12.5mm wide DIN rail housing offers a relay output with NO function.
The pluggable terminal strips enable simple and time-saving wiring. Configuration is also quick and easy with the DIP switches on the front.
