VT-HNC100-1-20A/W-08-I-0/IBUS12

Product Description:

The VT-HNC100-1-20A/W-08-I-0/IBUS12 comes from the Bosch Rexroth VT-HNC Digital Axis Controllers line and is built in a Euro-card format layout — a standard 100 x 160 mm board size. The weight stays low, around 0.23 kg, which means less load on racks or slots where it's mounted. It runs at a supply of 24 VDC, so it fits into low-voltage control systems that don’t pull heavy current. The current draw maxes around 2 A, depending on connected load and conditions.

Signals come through analog and digital inputs, with support for fieldbus-compatible setups. The data interface uses RS232 / IBUS, which helps it connect to existing factory controllers without needing protocol converters. For motion commands or feedback, the IBUS12 fieldbus handles communication between the drive and PLC layers. Not the most modern interface out there, but still dependable in legacy or cost-sensitive machines. PWM switching sits near 300 Hz, not super high, but good enough for smooth response in typical automation cycles.

The operating range falls between 0°C and +50°C, so this controller stays in place in regular indoor environments. It’s not protected against water or heavy dust though — an IP20 rating only — so not for exposed installs or anywhere outside cabinets. One control channel onboard (1 channel) means it’s intended for simpler systems with limited motion axes. Mostly used in older packaging setups, test benches, or retrofit panels where a full servo controller isn’t needed. Just solid signal handling in a compact format, with reliable communication and basic protections. It doesn’t have extras or fancy diagnostics, but it doesn’t need them either. The thing just works. It keeps motion smooth without making the system overcomplicated. Built for function, not flash.
