Connection Example and Specifications of Input Signals (HWBB Signals)
A connection example and specifications of input signals (HWBB signals) are shown below.
(1) Connection Example
(2) Specifications
The input signals (HWBB signals) have the following electrical characteristics.
For HWBB function signal connections, the input signal is the 0 V common and the output
signal is the source output. This is opposite to other signals described in this manual. To
avoid confusion, the ON and OFF status of signals for HWBB function are defined as follows:
ON: The state in which the relay contacts are closed or the transistor is ON and current
flows into the signal line.
OFF: The state in which the relay contacts are open or the transistor is OFF and no cur-
rent flows into the signal line.
