Terminal name Description
V0 Power supply terminal for internal circuits
The two V0 terminals are connected internally.
G0 Power supply terminal for internal circuits
The two G0 terminals are connected internally.
V1 Power supply terminal for external input devices and test outputs
G1 Power supply terminal for external input devices and test outputs
V2 Power supply terminal for external output devices
G2 Power supply terminal for external output devices
IN0 to IN15 Safety input terminals
T0 to T3 Test output terminals used to connect with safety inputs IN0 to IN15. Each test out-
put terminal outputs a different test pulse pattern. Terminal T3 also supports a cur-
rent monitoring function for the output signal, for example, for a muting lamp.
