The 5/48 Volt DC 0.5 Amp Negative Logic Output Module provides 32 output points in two isolated groups with 16 points in each group. This is a wide range module in that the rated voltage can be 5 volts DC or 10 to 60 volts DC. It provides a high degree of inrush current at 10 volts to 60 volts which makes the outputs suitable for a wide range of loads which have such characteristics. It also operates at TTL levels. LED indicators which give the ON - OFF status of each point on the logic (PLC) side of the circuit are located at the top of the module. The module is mechanically keyed to ensure correct replacement with a similar module 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.
