ADAM moduleADAM-4000 modules are the perfect choice for establishing a cost-effective and reliable remote data acquisition and control system. Customers can benefit from ADAM-4000 modules through its simple wiring - using only two wires to communicate with their controller or other RS-485 devices. ADAM-4000 modules use the EIA RS-485 communication protocol - the industry's most widely used bi-directional, balanced transmission line suitable for industrial environments. This simple wiring scheme enables rapid and economical deployment of a distributed data acquisition and control system suited to industrial environments. As the modules can be configure to use either a simple ASCII command/response protocol or the industry standard MODBUS protocol virtually any SCADA software package can be configured to interface to the ADAM-4000 series devices. A comprehensive range of modules covers most Analog input and output, Digital input and output and counter timer/frequency requirements. Modules can be DIN rail or panel mounted and can also be stacked in a piggy-back configuration. Power requirements are 10 ~ 30VDC and the average module requires approximately 2W.
