The 24/48 Volt DC 0.5 Amp Output Module for the Programmable Logic Controller (PLC) provides 32 output points in four isolated groups of 8 points each. This output module provides a high degree of inrush current which makes the outputs suitable for a wide range of loads which have such characteristics. LED indicators which give the ON-OFF status of each point on the logic (PLC) side of the circuit are located together at the top of the module. The module is mechanically keyed to ensure correct replacement with a similar type in the field. I/O references are user configurable without the use of jumpers or DIP switches on the module. Configuration is done using the configuration function of the MS-DOS or Windows programming software running on Windows 95 or Windows NT over Ethernet TCP/IP or through the SNP port. The Programming Software configuration function is installed on the programming device. The programming device can be an IBM XT, AT, PS/2 or compatible Personal Computer.
