Acromag offers relay interface modules for monitoring or controlling high power (on/off, high/low, on/off) drives using remote I/O, PLCs, or other distributed control systems with DC logic signals.
Wixom, MI, May 8, 2013 /PRNewswire/ — Acromag’s new BusWorks® XT series of multi-channel optocouplers and plug-in relay modules connect discrete field devices to the I/O module of a measurement and control system. The XTA-120V-6 optocoupler module provides six independent, isolated 120VAC/DC digital (discrete) inputs for detecting on/off levels and providing 5-32VDC logic outputs for input modules or fieldbus controllers. The XTA-MRNO-6 plug-in relay module accepts 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 provide a cost-effective, high-density solution that supports only low-level DC signals. Prices start at $150 for mechanical relay output modules and $180 for optocoupler input modules.
“These multi-channel discrete contact and relay output modules provide a secure, isolated interface between high-energy field devices and sensitive control system I/O modules,” explained Don Lupo, Director of Sales and Marketing, Acromag Technology Products Group. “By adding optocouplers and relays, you can use a PLC, DCS, or remote I/O module with 5-24V logic to control a 120V AC/DC contactor.”
The XTA-120V-6 six-channel optocoupler is designed for use with control system discrete input modules to monitor contact closures or power on/off voltage levels. Each channel detects the presence or absence of a high-level voltage to determine the status of proximity switches, limit switches, toggle switches, buttons, contacts, and other devices. The opto-isolator controls the MOSFET switch to achieve a TTL output level for a safe state interface of the monitored device.
The XTA-MRNO-6 six-channel mechanical relay is used with digital output modules to control high power loads. The block is used as a temporary digital interface for switching high voltage, high current devices based on DC digital logic inputs. Each output has normally open Form A (SPST-NO) mechanical relay contacts. LEDs on each channel display output status for easy troubleshooting.
Both modules can control audible or visual alarms. Common uses include chimney lighting, bells, whistles, lamps, and horns. The XTA-MRNO-6 is designed to switch inductive AC/DC loads at high currents, while the XTA-120V-6 is designed to control low current devices such as solid state relays, LEDs, relay coils, solenoids and incandescent lamps.
The innovative housing design is only 22.5mm wide and features removable front terminal blocks for easy wiring. All units are powered by 12-32VDC at the terminals or via an integrated power connector that connects along the DIN rail to provide primary or backup power. Failover is supported. The modules are suitable for use in harsh environments, with a -40 to 85°C operating temperature range, 1500 VAC isolation and surge/transient protection. They can also withstand 25 grams of shock and 4 grams of vibration. CE and UL/cUL Class 1, Division 2, Zone 2 Hazardous Locations pending.
