Product Description:

The VCH02.2NNN-000RS is a compact control terminal manufactured by Bosch Rexroth Indramat within the VCH IndraControl Terminals series. As an operator-mounted unit, it provides discrete signal handling for motion platforms and safety interlocks in automated cells. Its circuitry connects directly to logic-level controllers and converts field switch states into clean TTL-compatible signals. By integrating the terminal close to actuators and sensors, wiring runs are shortened and cabinet space is saved, allowing I/O functionality to be distributed across the machine.

The terminal runs on an operating supply of DC 5 V ±0.25 V, aligning with typical backplane voltages in IndraControl racks. Under this supply, it draws up to 20 mA on any individual input, while total draw stays below 90 mA, which minimizes load on the system power rail. Input transitions are captured with a maximum rise or fall time of 2 µs, so status changes are relayed without noticeable latency. A pulse train can be processed up to 5 kHz, meaning shaft-encoded positions and rapid proximity events remain within detectable bandwidth. Logic high is recognized above 2.5 V and logic low below 0.5 V, keeping compatibility with standard CMOS outputs.

The housing withstands axial forces up to 10 N and radial forces up to 20 N, so encoder wheels or stop cams can be mounted directly on the shaft without overloading the bearings. When fitted to rotary fixtures, the internal sensing disc can track rotations up to 200 rpm, while an integral stop switch carries loads from 5 V at 1 mA to 30 V at 1 A for emergency cutoff loops. During transport, the terminal survives shocks of 980 m/s² for 6 ms and endures vibration levels of 50 m/s² across the operating spectrum. With a weight of 0.6 kg, it can be mounted on light brackets without adding excessive inertia.
