Contact Inputs
• Purpose: Program pattern no. selection, and run/reset switching
• Number of inputs: 7 points
• Input type: Non-voltage contact or transistor open collector input
• Input contact rating: 12 V DC, 10 mA or more
• On/off determination: For non-voltage contact input, contact resistance of 1 k or less
is determined as “on” and contact resistance of 20 k or more as “off.”
For transistor open collector input, input voltage of 2 V or less is determined as “on”
and leakage current must not exceed 100
A when “off.”
• Minimum status detection hold time: PV input’s sampling period 3
Contact Outputs
• Purpose: Event output, FAIL output, and others
• Number of outputs: 7 points
• Relay contact rating: 240 V AC, 1 A, or 30 V DC, 1 A
• Transistor contact rating: 24 V DC, 50 mA
Display Specifications
• PV display: 5-digit, 7-segment, red LEDs, character height of 20 mm
• Setpoint display: 32 128 dot LCD with back lighting
• Status indicating lamps: LEDs
