Power Supply
Characteristics The power supplied to the Unit, to feed the Digital Outputs, has to be supplied
externally and should be a double insulated class II (over-voltage) type with rat-
ings from 12 to 24 VDC (10.2 to 26.4 VDC). Characteristics of the Power Supply
Input circuitry are summarized in the following table.
1-4 Quick Start Up Reference Guide
Operation and
Configuration Every Counter of the High-speed Counter Unit can be configured as Simple, Cir-
cular or Linear Counter (refer to the next section 1-5
"Operating Procedure Guide-
lines" for quick start up information).
Counters configured as Circular/Linear Counter can use all the functions and fea-
tures that the Unit offers to you, while Counters configured as Simple Counter only
offer you a limited subset instead. The diagram below shows you all the functional
blocks that the Unit has available to you to operate and configure the Unit (refer to
"Operation and Configuration" ). The numbers in grey refer to the table on page 16
to indicate which functions are supported for Simple Counters and which functions
for Circular/Linear Counters.
