Turck BL20-2DO-R-CO Digital Relay Output Module

The TURCK BL20-2DO-R-CO digital relay output module expands the BL20 I/O system with two changeover relay outputs (SPDT) for wiring field devices and control circuits. Each channel switches up to 250 VAC or 30 VDC, at up to 2 A, with 24 VDC supplied via the BL20 backplane bus and galvanic isolation from the field side through optocouplers. This plug-in module for the BL20 base system supports fieldbus-independent operation, integrated diagnostics (channel status LEDs), a hot-swappable design, and isolated changeover relay outputs suitable for relaying motors, contactors, valves, alarms, and other industrial control devices in packaging lines, conveyors, and automated assembly equipment. The module carries IP20 protection, operating temperature 0°C to +55°C, screw terminal or cage clamp connections, and approvals CE, cULus, FM Class I Division 2, ATEX, and IECEx.
