The 57400 model is an AC/DC input module which Reliance Electric was responsible for bringing to the market. The 57400 AC/DC input module is not in production anymore. Despite this, AX Control may still have the 57400 AC/DC input module in stock. If you have any questions about the availability or the process we undergo when shipping your order, please give us a call or send us an email during our regular business hours.
The 57400 AC/DC input module is typically used as a means to input on/off signals from certain devices. These devices, for example, can be push buttons, relay contacts, selector switches, and limit switches. The 57400 AC/DC input module is designed to accept up to sixteen 115 VAC or VDC control signals as inputs to the AutoMax system. The input signals possess 2500 Volt isolation to the logic common and may be 50/60 Hertz AC or DC. Lastly, the module contains a total of four isolated commons. Each of these isolated commons have a total of four inputs.
The 57400 AC/DC input module contains a printed circuit board, the faceplate, and the protective housing. This device is meant to plug into the back of the AutoMax rack. The input module has 16 input circuits for the 115 Volt AC/DC logic signals and each group of four circuit share a single isolated common.
Installation of the 57400 AC/DC input module is relatively simple. First, you will need to turn the system’s power off. This includes the power to the rack and its wiring leading. After that, you must mount a terminal strip onto a panel. When you are mounting the terminal strip, make sure that the terminal strip is mounted close enough to the rack so that its cable will reach the module and terminal strip. Then, you can fasten field wires to this terminal strip. After this terminal strip is mounted onto the panel, you may then insert the 57400 AC/DC input module into the slot of the rack you want. Attach the field terminal’s connector to the module’s mating half. When all of that is finished, ensure that connector keys are properly oriented. Finally, you may turn on the power to the system.
