The underlined values are the default settings. The set values are retained even after the instrument is turned o󰀨.
Input signal Signal type TRIG, V_CHECK, C_CHECK, OPEN, START, STOP, CLEAR,
INTERLOCK, KEYLOCK

HI, IN, LO, PASS, FAIL, ERR
Photo-coupler
isolation
Open drain output (Non-polar)
Maximum load
voltage
30 V DC
Residual voltage: 1 V or less (load current: 50 mA) / 0.5 V or less (load
current: 10 mA)
Maximum output
current
50 mA/channel
Output signal setting Operation details Sets the output of EXT I/O to current sink (NPN) or current source
(PNP).
Setting
NPN/PNP
Setting method Switches the setting using the rear switch. (Commands cannot be
used for switching the setting.)
TRIG lter function Operation details Processes signals only when the input signal remains in the on state
during the response time.
Setting
ON/OFF
Response time
1 ms to 500 ms
TRIG logic setting Operation details Sets the start edge for the TRIG signal.
Setting
ON edge/OFF edge
EOM output timing
setting
Operation details
Setting the output mode to HOLD leaves the EOM signal outputting in
the on state until the next TRIG signal.
Setting the output mode to PULSE leaves the EOM signal outputting
in the o󰀨 state after the period of the set pulse width has elapsed.
Setting HOLD/PULSE
Pulse width
1 ms to 100 ms (Accuracy: ±1%)
EXT I/O test function Operation details Displays the input signal status of EXT I/O, and optionally outputs an
output signal.
Service power
