I/O Modules

3.2 ADAM-4012 Analog Input Module

The ADAM-4012 Analog Input Modules use a microprocessor- controlled integrating A/D converter to convert sensor voltage or current signals into digital data. The digital data are then translated into either two’s complement hexadecimal format or percentage of full-scale range (FSR) according to the module’s configuration. When prompted by the host computer, the data are sent through a standard RS-485 interface.

The ADAM-4012 Analog Input Modules offer signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from power surges at the ground terminal by providing opto-isolation of the A/D input and up to 3000 VDC

transformer based isolation.

Digital Inputs/Outputs

The ADAM-4012 also contains two digital outputs and one digital input. Outputs are open-collector transistor switches that may be controlled by the host computer. They can control solid-state relays, which can be applied to heaters, pumps, and other electrical powered equipment. The digital inputs may be read by the host computer and used to sense the state of a remote digital signal.

Event counting

The event counter is connected to the Digital Input channel and can be used to keep track of the total amount of external low-speed pulses. Its accumulated maximal count is 65535. The number 65535 is held even if the actual number of events exceeds 65535. The counter can be read or reset to zero by the host computer.

Since the Event counter’s data are not stored in EEPROM, the event counter is cleared and set to zero after every reset or start up of the analog input module.
