Selected product option for Switch amplifier. All information below applies to the selected product option.
Applications that need clear switching status and flexible relay contact behavior benefit from reliable signal separation at cabinet level. TS225 converts and isolates digital switching signals from contacts, NAMUR initiators according to DIN EN 60947-5-6 and passive electronic outputs.
The 22.5 mm DIN rail housing provides relay outputs with changeover function, giving control systems access to both normally open and normally closed contact behavior. Single-channel and dual-channel versions are available, with DIP switches for direct or inverted output operation.
Optional line monitoring supports safer operation by detecting wire break below 0.2mA and short circuit above 7mA. In fault cases, the relays open and the front LEDs indicate the error. Selected versions support intrinsically safe inputs for hazardous-area sensors, and the devices can also be used in SIL2 systems.
The devices accept passive encoders, switching contacts, NAMUR initiators according to DIN EN 60947-5-6 and passive electronic outputs from third-party devices.
TS125 versions provide relay outputs with closing function. TS225 versions provide relay outputs with changeover function.
The family includes single-channel and dual-channel versions. A single-channel version with a second relay is available for use as a parallel relay or fault relay.
Front DIP switches set direct or inverted output behavior and activate error monitoring for the corresponding input channel.
When monitoring is activated, the device evaluates current thresholds for open circuit and short circuit conditions and indicates errors via the front LEDs.
TS125M and TS225M versions use a wide-range supply. TS125L and TS125LP versions operate with 24V DC +/- 15 %.
TS125LP versions can be supplied via a Power Rail DIN rail adapter, using a bus system in the carrier rail to simplify wiring for multiple devices
Versions with intrinsically safe inputs are available for connection of suitable sensors in hazardous areas, subject to the specified safety-related key values.
