5. External control interface
Connector 4-pin screwless terminal block ×1
Details External event input: input terminal [IN] ×1, ground terminal [GND1] ×1
External event output: output terminal [OUT] ×1, ground terminal [GND2] ×1
Event Input Recognizes as an event input by the fall in the pulse signal or the short-circuiting (active
LOW) of the GND1 terminal and the IN terminal each other.
Non-insulated (GND1 is common with this instrument ground)
Maximum rated power between terminals: 45 V DC
Voltage input (High: 2 V to 45 V, Low: 0 V to 0.5 V)
High duration: 100 ms or more, Low duration: 100 ms or more
Event output Open Collector 30 V, max 5 mA (isolation using photo-couplers)
TTL low output at event generation between GND2 terminal and OUT terminal
Low-level output pulse
width
Short pulse: approx. 10 ms
Long pulse: approx. 2.5 ms
