For More Products
Print Print
See Product Details

This DIN rail mounted encoder interface lets you connect an encoder to a variety of controllers, or to multiple input devices. It provides an optically isolated signal and is available with one of four output driver options making it compatible with all major counter, drive and PLC components. Multiple modules can be daisy-chained together and drive as many as eight different devices from a single encoder.

The interface module also provides LED output indicators for two quadrature channels and an index. All circuitry for the module is packaged in a housing that mounts to a standard external DIN rail. For ease of installation, a 75 mm length of DIN rail is supplied with each module.

Mechanical Specifications:

Package dimensions are 114.4 mm high by 99 mm wide by 22.5 mm thick. The package mounts to a DIN rail type EN50 022 (35mm X 7.5mm). A length of DIN rail is supplied with each module.

Electrical Specifications:

The optical isolator can be powered by an external power supply of anywhere from 5 to 24 VDC, depending on the model. It should never be connected directly to AC power mains. The module draws approximately 75 mA and a green LED indicates the unit is powered. The optical isolator module does not provide power to the encoder. Any encoders used in conjunction with this module must be connected to their own power supply.
