Acromag BusWorks XT Series multichannel optocoupler and interposing relay modules

Friday, 31 May, 2013 | Supplied by: Metromatics Pty Ltd

Acromag’s BusWorks XT Series multichannel optocoupler and interposing relay modules connect discrete field devices to measurement and control system I/O modules. The XTA-120V-6 optocoupler modules have six individually isolated 120 VAC/VDC digital (discrete) inputs to sense on/off levels and provide 5-32 VDC logic outputs to a fieldbus input module or a controller. The XTA-MRNO-6 interposing relay module receives 4-32 VDC logic-level signals from an output module or controller to switch six mechanical relay outputs. These two high-voltage relay interface modules offer a high-density, cost-effective solution to safely monitor or control inductive and other high-power loads (such as motors, valves and solenoids) with control system I/O modules that only support low-level DC signals.

These multichannel discrete contact sensor and relay output modules offer a safe, isolated interface between high-energy field devices and sensitive control system I/O modules. By adding optocouplers and relays, users can use PLC, DCS, or remote I/O modules with 5-24 V logic circuits to operate 120 VAC/VDC contactors.

Both modules can drive audible or visual alarms. Common uses involve operation of stack lights, bells, whistles, lights and horns. While the XTA-MRNO-6 is intended for switching AC/DC inductive loads at high currents, the XTA-120V-6 is designed to drive low-current devices such as solid-state relays, LEDs, relay coils, solenoids and incandescent lamps.

The housing is only 22.5 mm wide and features removable front-facing terminal blocks for easier wiring. All units run off a 12-32 VDC power source at the terminals or through an integrated DIN-rail power connector. Fail-safe operation is supported.
