B&R X20 DC 1198 Counter Module – SSI Absolute Encoder Interface

The X20 DC 1198 is a counter module from the B&R X20 series, designed for interfacing with SSI absolute encoders. It provides one SSI encoder input (5V differential) with 32-bit counter resolution, plus two additional digital inputs (24 VDC) for auxiliary signals. The module supports high-speed position feedback and velocity measurement applications with a maximum transmission rate of 1 Mbit/s.

Key Features:

· 1 SSI absolute encoder input (5V differential)
· 2 additional digital inputs (24 VDC)
· Counter size: 32-bit
· Maximum transmission rate: 1 Mbit/s
· Encoder power supply: 5 VDC / 24 VDC, max 300 mA
· Bus interface: X2X Link
· Power supply: 24 VDC (-15% / +20%)
· Power consumption: 0.01 W (bus), 1.5 W (internal I/O)
· Operating temperature: -25°C to +60°C (horizontal installation)
· Protection class: IP20
· Module width: 12.5 mm (1.25 cm)

Applications:

· High-precision position feedback
· Speed measurement and monitoring
· Length measurement in cutting and packaging machines
· Rotary table positioning
· Industrial automation requiring absolute encoder interface

Compatibility:
Requires a bus module (X20BM11) and a terminal block (X20TB12) for proper operation. Compatible with B&R X20 systems.
