General
Interrupt ControllerWhen enabled by software, interrupts are generated when any isolated digital input changes state (High to Low or Low to High, and from signal to no signal with AC inputs).
System

Voltage Range: 3 to 31V DC or AC RMS (50 to 10KHz)
Isolation: 500V
Input Resistance: 1.8KO in series with an opto-couple
EnvironmentAmbient Temperature: Operating: -30°C to 70°C (Non-Icing)
Weight: Approx. 4 oz. (~115 grams)
Power Consumption+5VDC at 0.4A (all relays ON)
RTCNumber of Outputs: Eight
Type: SPDT Form C Relay - Omron G5V-1
Contact Ratings: 1A @ 24VDC (60VDC max), 0.5A @ 125VAC carry current
Contact Type: Single crossbar Ag with Au clad (bifurcated contacts optional)
Contact Arrangements: Channels 0-

Features:

  • 8 long-life form C electro-mechanical relays switch up to 1A each
  • 8 non-isolated TTL compatible inputs
  • 8 optically-isolated, non-polarized CMOS compatible digital inputs accept ±31VDC or AC rms
  • IRQ on input change of state (COS) eliminates the need for constant polling
  • Slow/fast filter to accommodate AC voltages and noisy DC inputs
