The Allen-Bradley 1492-XIM24-16RF module is an expander module with sixteen 24 Volts DC rated relays with fusing. The 1492-XIM24-16RF module is part of the Bulletin 1492 product range which includes digital/analog programmable controller wiring systems. The mechanical specifications for the 1492-XIM24-16RF module include 933 grams of weight and dimensions of 11.05 x 3.27 x 2.74 inches. Environmental specifications include a working temperature range of 0 to 60 degrees Celsius and 5 to 95% relative humidity. The 1492-XIM24-16RF module complies with multiple standards including the CE, cULus, and FM class 1 Div 2 Groups A, B, C and D standards. The temperature rating for the module is T3C or 60 degrees Celsius maximum. The performance specifications include 600 Volts of peak recurring voltage, 2 milliamps of indicator current, and a 20 to 26 Volts DC voltage range.

Relay expander modules such as the 1492-XIM24-16RF module were developed to improve the effectiveness of user applications that require output contact ratings greater than 2 Amps. For proper module operation, the specified current and voltage ratings for the module should not be exceeded. The 1492-XIM24-16RF module must be used with a 24 Volts DC relay master. The LEDs on the module provide output ON/OFF indication. Bulletin 1492 products such as the 1492-XIM24-16RF module are compatible with a number of programmable controllers from Allen-Bradley, including the Bulletin 1756 ControlLogix, 1771 PLC-5, 1769 CompactLogix, and 1746 SLC 600 controllers. For the installation of the 1492-XIM24-16RF module, a DIN #3 rail is required. Information related to field wiring is included on the printed adhesive label cards which are provided with each module. The major benefit of the 1492 series products is reduced wiring time and faster system deployment.
