Function (Signal Level)
• Response frequency: 0 Hz to 32 kHz
• Heavy duty: 30% to 70%
• H level voltage: 3.5 V to 13.2 V
• L level voltage: 0.0 V to 0.8 V
• Input impedance: 3 kΩ
Voltage input or current input
Select terminal A1 using DIP switch S1-1 and H3-01 [Terminal A1 Signal
Level Select].
Select terminal A2 using DIP switch S1-2 and H3-09 [Terminal A2 Signal
Level Select]
• -10 V to +10 V/-100% to 100%
• 0 V to 10 V/100% (input impedance: 20 kΩ)
• 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance: 250 kΩ)
• Voltage input or current input
Select using DIP switch S1-3 and H3-05 [Terminal A3 Signal Level
Select].
– -10 V to +10 V/-100% to 100%
– 0 V to 10 V/100% (input impedance: 20 kΩ)
– 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance: 250
kΩ)
• PTC input (Motor Overload Protection)
Set DIP switch S4 to "PTC" and set DIP switch S1-3 to "V" to set terminal
A3 for PTC input.

Function (Signal Level)
• Relay output
• 30 Vdc, 10 mA to 1 A
• 250 Vac, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)
• Relay output
• 30 Vdc, 10 mA to 1 A
• 250 Vac, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)
Note:
Refrain from assigning functions that frequently switch ON/OFF to
terminals M1 and M2, as doing so will shorten relay contact
performance life. Switching life is estimated at 200,000 times (assumes
1 A, resistive load).
• Photocoupler output
• 48 V, 2 mA to 50 mA
Note:
Connect a flywheel diode as shown in
reactive load such as a relay coil. Ensure the diode rating is greater than
the circuit voltage.
