Product information
Overview
Applications
- Encoder counting: Supports counter functions for 5 V and 24 V incremental encoder signals, including symmetrical and asymmetrical incremental encoders.
Key Features
- Counter capacity: 1 counter input with 32 bit or ±31 bit resolution; counting frequency is up to 500 kHz for 5 V input and up to 200 kHz for 24 V input.
- Encoder connection: Connects symmetrical or asymmetrical incremental encoders, 24 V initiators, and 24 V directional elements.
- Digital I/O: Provides 3 digital inputs for gate start, gate stop, and counter setting, plus 2 digital outputs.
- Encoder supply: Provides 5.2 V ±2 % with output current up to 300 mA, or 24 V at 1L+ (-3 V) with output current up to 400 mA.
- Interfaces and mounting: Uses 1x 20-pin front connector; dimensions are 40 mm wide, 125 mm high, and 120 mm deep.
- Protection and isolation: Digital inputs, digital outputs, and the counter have optocoupler isolation between the channels and backplane bus; digital outputs have electronically clocked short-circuit protection.
