The AXM-22-0-0 is an expansion module designed for the ACM Power Unit, featuring 22 jumper-selectable inputs including 12-bit universal inputs that support thermistor, dry contact, 0-5VDC, 4-20mA, or 0-10VDC signals. Inputs 1, 2, and 3 also support pulsed inputs with a 10 msec minimum pulse length, and no external resistor is required for 4-20mA signals. The unit requires a 24 VAC, 50-60Hz, 20VA minimum half-wave rectified power supply, with output loads powered separately. For installation and communication, it utilizes removable header-type screw terminals to simplify field wiring and a twisted pair, multi-drop AXM communications bus to the ACM base unit. Measuring 6.95 inches high, 4.95 inches wide, and 1.6 inches deep, this module operates reliably in environmental conditions ranging from 32 to 131 degrees Fahrenheit and 0 to 95 percent relative humidity, non-condensing.
