Terminal function description
Supply +10V power to external devices.
Maximum output current: 20mA
Supply +24V power to external devices. It is
usually used as the working power supply for
digital input and output terminals and also the
power supply for external devices. Maximum
output current: 100mA
Input voltage range: DC 0-10V; input
impedance: 1MΩ
Input range: DC 0-10V/0-20mA. The
voltage/current mode is selected via the switch
S2 on the control panel.
Input impedance: 1MΩ in the voltage mode
and 250Ω in the current mode
