Page 4: Description
Symbols on equipment: The XTA‐MRNO‐6 is a six channel digital input board with six, normally open, isolated mechanical relay outputs for use with BusWorks XT Series DIO modules, or other digital output modules, for the purpose of driving high energy loads. This module serves as an interim digital interface for driving high voltage (up to 250VAC, Means “Refer to User’s Manual... -

DIN rail clip and use it as a lever to force the DIN rail spring clip down while pulling the bottom of the module outward until it disengages from the rail. Tilt the module upward to lift it from the rail. Acromag, Inc. Tel: 248‐295‐0880 http://www.acromag.com... -

(use 0.5‐0.6nM torque). Since common mode voltages can exist on I/O wiring, adequate wire insulation should be used and proper wiring practices followed. As a rule, I/O wires are normally separated from power and network wiring for safety, as well as for low noise pickup. Acromag, Inc. Tel: 248‐295‐0880 http://www.acromag.com... -

DIN rail bus when coupled to the DIN rail bus connector (Acromag Model 1005‐070) and a bus terminal block (Acromag 1005‐220 or 1005‐ 221). This optional method can allow several modules to share a single power supply without wiring to each individually. - Page 8 Important – End Stops: If this module uses the optionally powered (or redundantly powered) via the DIN rail bus for hazardous location installations (Class I, Division 2 or ATEX Zone 2) it must use two end stops (Acromag 1027‐222) to secure the terminal block and module (not shown).
