Pulse Input Module
This module is Version 3 and introduces a new style connector header.
Version 3 modules may be used in the old Version 2 or Version 1 rack together with
the enclosed new connector header.
Description
This module provides 2 channels for general purpose high speed counting and
totalising applications, and a supply for powering encoders.
A variant of this module permits decoding of quadrature encoders.
The module can handle pulse inputs up to 200kHz.
All data in this chapter refers to the later 'Mk 2' pulse input module.
The inputs have reinforced insulation to the "System" and other modules.
There is no inter-channel isolation.
Caution live sensors
Where one channel may be live, the installer must ensure that the other channel in the
same module, is not accessible to service personnel while it is live. The installer must
also ensure that this situation will not damage other connected equipment. All cables,
connectors and switches for connecting external equipment to an I/O point that may
be at live potential, must be mains rated.
