Astronics / EADS / Racal 1260-12 Actuator Relay Module

The Astronics/EADS/Racal 1260-12 Actuator Relay Module is a 20-channel signal switching component for aerospace and industrial control applications. Each channel provides Double-Pole, Double-Throw (DPDT) relay switching up to 220 VDC or 250 VACrms at 2A maximum. Channels operate independently or combine for complex switching networks, with built-in relay coil confidence monitoring to verify proper operation. ## Technical Specifications Switching Capacity (Per Channel) • Maximum voltage: 220 VDC or 250 VACrms • Maximum current: 2A (DC or ACrms) • Maximum power: 60W (DC) / 62.5VA (AC) • Path resistance: 200 mΩ at 2A • Isolation: >10⁹ Ω AC Performance (50Ω) • Bandwidth: 35 MHz typical (-3dB) • Capacitance (open channel, channel-chassis): <25 pF • Insertion loss: <0.2dB @ 100kHz, <0.25dB @ 1MHz, <0.5dB @ 10MHz • Crosstalk: <-75dB @ 100kHz, <-60dB @ 1MHz, <-40dB @ 10MHz Physical & Environmental • Channel count: 20 DPDT relays • Cooling requirement: 1.0 liters/sec airflow • CE Mark compliance: European electrical safety standards, RF emissions, electromagnetic immunity ## Key Features • Configurable relay networks - join channels or operate independently • User-selectable confidence checking on relay coils • Message-based control interface (Option 01) • Simple command syntax: CLOSE . ## Typical Applications • Aerospace signal routing and circuit control • Industrial switching and device management • Complex control systems requiring precision relay matrices • Multi-channel circuit configuration and reconfiguration ## Compatibility & Integration Designed for integration with mainframes and carriers supporting the Option 01 message-based interface. Distinct from related 1260 series modules: the 1260-120 offers SPST high-power switching (up to 13A @ 250VAC or 10A @ 125VDC); the 1260-112 provides high-density DPDT with 120 MHz bandwidth for digital and differential analog signals.
