Product Description:

The VT-VPCD-1-17-V0/1-0-1 is a plug-in controller card manufactured by Bosch Rexroth Indramat for the VT-VPCD Drives series. Supplied from a nominal 24 VDC control circuit, the card conditions analog signals, switches digital outputs, and exchanges data through an RS-232 service port. By combining these functions on a single module, it simplifies the coordination of drive components and other automation devices that share the same low-voltage cabinet supply. Its plug-in format also supports straightforward integration into compatible rack or back-plane assemblies.

The card draws up to 3.5 A under peak load and is protected by an internal 4 A fuse with a 250 V clearing voltage. Logic and sensor circuits remain stable because the permissible supply spans from 21 V to 30 V, with a nominal value of 24 VDC. The analog input stage presents 100 kΩ of resistance, minimizing loading on external transducers, while the voltage output section can drive loads down to 1 kΩ. Current inputs are digitized every 2 ms, and the same cycle time is used for program scans so process variables and control words are refreshed coherently. Individual digital outputs can source up to 30 mA, which is suitable for optocoupler boards, interface relays, and diagnostic lamps with low current demand.

Signal resolution is precise, with voltage outputs changing in 10 mV (11 bit) steps, and current inputs converting with 5 µA granularity at 12-bit depth while limiting leakage to 0.15%. No fieldbus interface is included, but parameterization and service access are available through an RS-232 channel that terminates on a D-Sub 9-pole socket. Back-plane integration is achieved through the 64-Pin DIN 41612 Form G edge connector, and a front display provides local status viewing at the module face. The controller operates between 0 °C and a maximum ambient temperature of 50 °C. Internal circuits use a 100 Ω current-input shunt to maintain measurement accuracy throughout that operating range.
