Accu-Coder Encoders

EPC is known for offering a well-rounded line of rotary encoders (and in the case of the Cube series, well-squared.). But, in addition, we also offer a plethora of encoder accessories, including the RX/TX line of signal conditioners, transmitters and receivers. EPC now introduces the next generation RX/TX product with the release of the all new RX/TXD.

Accu-Coder RX/TXD Signal Conditioners, Transmitters & Receivers Distributors


This lightweight DIN rail mountable unit, Line Driver and Line Receiver, comes in a stylish green PC/ABS self-extinguishing material blend. Configurable as a level changer, line repeater, splitter or encoder tester. The RX/TXD will accept TTL, RS422, RS485, PP, NPN, NPN OC, or, PNP encoder inputs at 5V, or HTL, PP, NPN, NPN OC & PNP at 6-28V. It will provide up to 3 outputs in any combination of TTL, RS422, RS485, PP, NPN or PNP, at 5V, or, HTL, PP, NPN or PNP, at 6-28V.

A series of LEDs on the front panel indicates power and signal presence. Connections are made via the easily accessible screw terminals as standard. This device may be used as both a Line Driver and Line Receiver.

Features & Benefits:

  • The RX/TXD provides versatile encoder signal conditioning and transmission capabilities by combining multiple functions into a single unit.
  • Configurable as level changer, signal converter, line repeater, splitter, or tester
  • Splits one input signal into two or three outputs
  • LED indicators for encoder power and signal presence
  • Accommodates a variety of digital signal types (RS422, NPN, PNP, TTL, etc.) and voltages (5VDC or 6-26VDC) as both input and output options, allowing for use with all EPC products as well as other encoder brands
  • Compact and lightweight DIN Rail mountable PC/ABS housing for easy and versatile installation
  • All connections can be made via easily accessible screw terminals

Normally, encoders are configured to provide the correct digital outputs which then feed directly to a counter, controller, or other device. However, some applications require additional measures to optimize the encoder signal for the receiving device. In such cases, EPC's RX/TX products enable customers to modify, split or repeat the signal. Our new RX/TXD combines all of these capabilities into a compact DIN rail mountable unit.

Here's an overview of these capabilities and how they might be applied:

Signal Converter - In many retrofit or upgrade projects, existing rotary encoders may need to interface with newer devices with mismatched input requirements. In these cases, the RX/TXD's level changer/conditioner capability is ideal. For example, a 24VDC open collector output can be converted to a 5VDC RS422 compatible differential line-driver, an output type better suited for long cable runs or electrically noisy environments.

Signal Splitter - When a single encoder must provide signals to multiple devices, the RX/TXD can split one signal into two or three identical outputs. This capability can eliminate the need for redundant encoders and also offers greater design flexibility.

Signal Repeater - For encoder signals transmitted over long distances, the RX/TXD can be configured as a signal repeater, eliminating the risk of voltage drop and ensuring signal integrity. The RX/TXD accommodates a variety of digital signal types (RS422, NPN, PNP, TTL, etc.) and voltages (5VDC or 6-26VDC) as both input and output options, allowing for use with all EPC rotary encoders as well as other brands.

Encoder Tester/Verifier - When troubleshooting a closed-loop control system, it's often beneficial to quickly determine whether or not the encoder is functioning properly prior to assessing other components. The RXTXD features a series of LED's on the front panel that indicate power and signal presence, enabling an encoder tester/verifier function.
