4.2.59 Intelligent output terminal a/b (NO/NC) selection
The intelligent output terminal a/b (NO/NC) selection function allows
you to specify a-contact or b-contact output for each of the intelligent
output terminals [11] to [15] and the alarm relay terminal.
The intelligent output terminals [11] to [15] are used for open-collector output, and the alarm relay terminal is used
for relay output.
- An a-contact turns on the output signal when closed and turns it off when opened.
- A b-contact turns on the output signal when opened and turns it off when closed.
(1) Specifications of intelligent output terminals [11] to [15]
Intelligent output terminals [11] to [15] have the following specifications:
15 CM2 … … 11
(2) Specifications of alarm relay terminal
The alarm relay terminal uses a normally-closed (NC) contact that operates as described below.
AL0 AL1 AL2
