Output signals and power supply for control
It is possible to take out each condition of the
8526
as output signal.
The power supply of 24V DC for control is provided, so the relay etc. can be directly
driven.
(1) Specification of output signal (Pin No.10~14, 24~26, 28, 31, 32)
Signal type
: Open collector output
Max. load voltage
: 30V DC
Max. output current
: 30mA DC
Isolation system
: Isolated from the internal circuit by photo-coupler
Output saturation voltage : 1.6V DC or less
(2) Specification of control power source (Pin No.1)
Output voltage
: 24V DC
Current capacity
: 0.1A DC

CAUTION
●
Use the output signal with 30V and 30mA DC or less.
●
In case of controlling an inductive load like relay, connect a diode in
parallel with the coil to absorb the reverse electricity.
