Encoder distributor, signal booster, cross switcher or splitter

Intro

The Motrona GV210 is a compact DIN-rail interface for incremental encoders. It converts, splits and switches encoder signals in one module. Use it to connect HTL encoders to RS422 drives, to send one encoder signal to two controllers, or to switch a controller between two encoders. Each of its two inputs and two outputs can be set to TTL/RS422 or HTL (10–30 V), so it adapts to almost any combination of encoder and controller.

Key features

• Three operating modes in one unit: dual level converter, splitter (one input to two outputs) and cross switcher
• Two encoder inputs and two outputs (A, /A, B, /B, Z, /Z), each set to TTL/RS422 or HTL
• Input frequency up to 1 MHz (differential) or 250 kHz (single-ended)
• Contactless, bounce-free switching between encoders by remote 24 VDC control signals
• 5 VDC auxiliary output to power the encoder
• 12–30 VDC supply with reverse polarity protection
• Slim 22.5 mm DIN-rail housing with screw terminals

Typical applications

• Upgrading a drive or motion controller to RS422 while keeping an existing HTL encoder
• Feeding one encoder to a VSD for speed control and to a PLC/HMI for position readout
• Selecting between two encoders on one display or controller
• Sharing one conveyor encoder between two machines with separate PLCs
