Contact No.
• Contact Nos. are input/output terminal Nos. of basic units, input expansion units,
output expansion units, and I/O expansion units.
• The contact No. is represented as a number 0 to 15.
Example
In the KV-E4X, with 4 input terminals, the contact Nos. are 0 to 3. In the KV-
E16T(P), with 16 input terminals, the contact Nos. are 0 to 15.
• In a unit with 16 or more terminals, the contact No. of the 17th terminal returns to
0 and its address No. is increased by 1.
Example
In the KV-40AR, with 40 terminals (24 input and 16 output terminals), address
No. 0 is assigned to input terminal Nos. 1 to 16 and address No. 1 is assigned to
input terminal Nos. 17 to 24
Channel No.
The channel No. is the higher order digit in the contact No.
1.3.3 Assigning Relay Nos.
When assigning relay Nos., the unit No. is based on the connection position of the
unit, and the address No. is determined based on the unit type and I/O contacts.
With the connections above, the relay Nos. for each unit are assigned as shown in
the table below.
a) KV-16AR
Basic unit
Input: 10 points
Output: 6 points
b) KV-E4X Input
expansion
unit
Input: 4 points
c) KV-E8R Output
expansion unit
Output: 8 points
Unit Assigned relay Nos.
a) KV-16AR 0000 to 0009 (input) and 0500 to 0505 (output)
b) KV-E4X 0100 to 0103 (input)
c) KV-E8R 0600 to 0607 (output)
