DIFFERENTIAL TO HTL CONVERTER
Description
Function
To convert TTL or HTL Pulse output from Single ended or Differential ended type Encoders into HTL format. When 24 VDC (18-30 VDC) Control Supply is connected, then 24VDC supply for HTL Encoders and 5VDC supply for TTL Encoders is provided through the unit. Galvanically & optically isolated Dual channel HTL outputs are provided to connect 2 different control units.
Suitable for very Low to High frequency inputs (from 1 Hz to 500 KHz). |
Selection of HTL or TTL input through toggle switch |
Both outputs are optically & galvanically isolated from input and each other. |
5VDC & 24 VDC supply are provided for powering the Encoder. |
