A90L-0001-0551#A Fanuc System Fan

Module Specifications

• Number of Output Points: 16 points

• Output Type: Relay (Form A - SPST-NO)

• SPST-NO: Single-Pole Single-Throw, Normally Open

• Electrical Isolation: Photocoupler isolation between the internal logic and the relay coils, and relay contact isolation between the output contacts and the internal circuits.

Electrical Characteristics (Output Side)

• Rated Load Voltage:

• 250 V AC / 250 V DC

• Maximum Load Current:

• 2 A per point

• 8 A per common block (The 16 points are typically grouped into commons, e.g., 8 points per common)

• Minimum Load Current:

• 5 mA DC / 0.1 mA AC (for reliable contact operation)

• Rated Carry Current: 5 A per point

• Contact Configuration: 1c (Single-pole) / SPST-NO

Relay Life

• Mechanical Life: 20,000,000 operations (min.)

• Electrical Life (at Rated Resistive Load):

• 100,000 operations @ 250 V AC, 2 A

• 100,000 operations @ 250 V DC, 2 A

• Note: Life expectancy decreases significantly with inductive or high inrush loads.

Response Time

• OFF → ON: Approx. 10 ms (Includes relay operate time and photocoupler response)

• ON → OFF: Approx. 12 ms

Internal Circuit (Drive Side)

• Rated Input Voltage (for relay coil): 24 V DC (sourced from the PLC's internal power supply or an external supply via the base unit)

• Operating Voltage Range: 21.6 V DC to 26.4 V DC

• Current Consumption (from 5V DC logic supply): Typically 0.1 A (from the PLC backplane)

Indicator LEDs

• Power Indicator (PWR): Lights when power is supplied to the unit.

• Output Indicators (LED 0 to LED 15): One for each output point, lights when the corresponding relay is energized (ON).

Environmental & Mechanical Specifications

• Operating Temperature: 0 to 55 °C

• Storage Temperature: -25 to 65 °C

• Relative Humidity: 5% to 95% (non-condensing)

• Vibration Resistance: Conforms to JIS B 3502, IEC 61131-2

• Shock Resistance: Conforms to JIS B 3502, IEC 61131-2
