Overview contains a short description of the RTAC-03 TTL Encoder Interface module and a delivery checklist. Installation contains instructions for module hardware settings, mounting and cabling. Fault tracing explains fault tracing and the LED indications of the RTAC-03 module.

Input terminals of the TTL input module (cat. no. 1771-IGD) may be directly driven by the outputs of a TTL output module (cat. no. 1771-OGD). Connect the cable shield between modules at one end only.

The EL5101 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential signals (RS422) or TTL single ended signals. Input frequencies up to 1 MHz can be evaluated.

The FEN-11 offers an interface for an absolute encoder with PTC/ KTY support and TTL encoder connection and a TTL encoder emulation output. It also supports two digital inputs for position latching. The following figure describes the different isolation areas of the module. The shields of sockets X41 and X42 and plug X43 are connected to chassis.

Our large selection of encoders allows you to control and position your plant according to your requirements: Incremental encoders with the conventional signal levels TTL (Transistor-Transistor Logic) and HTL (High Threshold Logic) Incremental rotary encoders with sin/cos tracks; Absolute encoders with RS485 and sin/cos tracks

TTL output encoders utilize differential signaling (such as A and /A, B and /B) to minimize noise interference, ensuring signal integrity over long distances. This differential approach effectively cancels out electromagnetic noise, making TTL output encoders ideal for harsh industrial environments. Types of TTL Output Encoders

The MAX14890E incremental encoder receiver contains four differential receivers and two single-ended receivers for RS-422, HTL, TTL, and digital signals. Power for the transceiver can be provided from a single +5V source or from an on-board 24V to 5V step-down circuit.

12 Hardware description The FEN-01 TTL Encoder Interface The FEN-01 offers an interface for two TTL encoder connections, one with commutation signals and PTC support. It also offers a TTL encoder output for emulation purposes and two digital latch inputs for position latching.

This manual contains the very basic information about installing the FEN-01 TTL Encoder Interface. For complete documentation see FEN-01 TTL Encoder Interface User’s Manual (3AFE68784603 [English]). WARNING! All electrical installation and maintenance work on the drive must be carried out by qualified electricians.

The MICROMASTER Encoder Module has been designed to allow the MICROMASTER 440 inverter to interface with the most common types of digital encoders. The Encoder Module can use High-voltage Transistor Logic (HTL) and Transistor Transistor Logic (TTL) digital encoders.
