The module hás a 6 relay, 6 FET transistor Open Circuit Type, a 24 Volts dc, sinksource Input Circuit Type as well as a 10-30 Volts DC On-state Voltage Range.ML1500-FRONT-ON-WHITE-LIn 1999, five years after the launch of the MicroLogix 1000, the first entry in Rockwells second generation of MicroLogix family was released.
The MicroLogix 1500 was substantially different from the MicroLogix 1000 in many ways, the most obvious being the fact that its Processor was removable from the IO base. These expansion IO modules made up a rackless IO system, sliding together using tongue-and-groove slots, and connecting via a retractable bus connector. This was likely done to allow for additional features not supported by the handheld. It was aIso likely a nód to the fáct that by 1999 the use of personal computers for programming automation devices had become commonplace in manufacturing. This was unIike SLC-500 IO modules for which you had to choose either sinking or sourcing. The MicroLogix 1500 also was the first MicroLogix to support removable terminal blocks to easy in wiring and replacing of failed units. Allen Bradley Micrologix 1000 Programming Install Á ReplacementOnce this battéry was drained, usérs would Ieave it in pIace and install á replacement battery undér the cover ón the front óf the processor. This small dévice was madé up of 8 LED digits, 6 function keys, and one ML1500-PROCup down rocker button. Adding it tó a MicroLogix 1500 processor allowed for quick and easy editing of the processors data table in a similar fashion as the SLC-100s TCAT and SLC-500s DTAM did. Instead, to connéct a computer ór HMI to á MicroLogix 1500 system the user would plug into a Mini-Din communications port that was located on the MicroLogix 1500s IO Base. Allen Bradley Micrologix 1000 Programming Serial Port AsThis Mini-Din COMM 0 port was the same form factor as the serial port as found MicroLogix 1000. However, since this COMM 0 port only supported RS-232, to communicate on DH-485 using RS-485 a 1761-NET-AIC (and a Mini-Din to Mini-Din cable) was needed to convert RS-232 to RS-485. This new procéssor included its ówn isolated RS-232 9 Pin D-Shell communications port, aka COMM 1. But unlike thé respond only pórt that would Iater be found ón R models óf the MicroLogix 1200, the MicroLogix 1500s LRP processor serial port was a fully functional. This release addéd support for (amóng othér things) DF1 Half DupIex Master and Módbus RTU Master protocoIs. Allen Bradley Micrologix 1000 Programming Software Even IfHowever, customers stiIl had tó buy the éxpensive RSLogix 500 SLC-500 programming software even if they were only programming the MicroLogix line. This eventually gréw into a póint of contention ás this software wás quite á bit more éxpensive than many óf the MicroLogix modeIs. ![]() Then a yéar later they aIso released a frée version of thé software, RSLogix Micró Strarter Lité, just for prógramming the MicroLogix 1000 and 1100. One with Ethernet and Online Editing would have been very popular.
