Chapter 3 Configuration PB-TIM2 User’s Manual

3.1.1 Input Electrical Specification

The 10 inputs (3 per counter and one common) are all optoisolated from the supply with a rating of 1500V. Isolation

between the inputs is rated at 100V. The inputs (A), (B) and (C) all have separated differential inputs while the common

clear is referenced to V-. The inputs are protected against reverse voltage and sink typically 15mA.

Note

For those customers possessing the PB-TIM2 without optoisolation for improved speed performance,

the TTL inputs need to be inverted to maintain the characteristics laid down in this manual.

The inputs may be configured to cater for different operational voltages and frequency limits.
