Analog External Control
Load on/off Control Input
Turn on the load with low (or high) TTL level signal
Load on Status Output
On when the load is on (open collector output by a photocoupler)
Range Switch Input
Switch ranges L, M, and H using a 2-bit signal
Range Status Output
Outputs range L, M, or H using 2-bit signal (open collector output
by a photocoupler)
Trigger Input
Clear the sequence operation pause with a high TTL level signal
for 10 μs or more.
Alarm Input
Activate alarm with low TTL level signal input
Alarm Status Output
On when OVP, OCP, OPP, OTP, UVP, RVP, or when an external
alarm input is applied (open collector output by a photocoupler)
Short Signal Output
Relay contact output (30 VDC/1 A)
External Voltage Control
Operates in CC, CR, CV, CP, or Cx+CV mode
0 V to 10 V correspond to 0 % to 100 % of the rated current (CC
mode), rated voltage (CV, Cx+CV mode), or rated power (CP
mode).
0 V to 10 V correspond to maximum resistance to minimum
resistance (CR mode)
External Resistance Control
Operates in CC, CR, CP, or CV mode
0 Ω to 10 kΩ correspond to 0 % to 100 % or 100 % to 0 % of the
rated current (CC mode), rated voltage (CV mode), or rated power
