3.1 ADAM-4011/4011D Thermocouple Input Modules

The ADAM-4011/4011D Thermocouple Input Modules use a microprocessor-controlled integrating A/D converter to convert sensor voltage, current or thermocouple signal into digital data. The digital data is 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 is sent through a standard RS-485 interface.

The ADAM-4011/4011D Thermocouple 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 transformer based isolation up to 3000 VDC. (ADAM-4011 has transformer-based isolation up to 500 VDC)

Open Thermocouple Detection and Input Surge Protection (ADAM-4011D only)

The ADAM-4011D provides an open thermocouple detection function. Users can use a simple command to detect whether the thermocouple is opened or closed. The module also provides surge protection on its input channel. Internal high-speed transient suppressor on its input channel protects the module from dangerous spikes and voltages.

Front Panel LED Indicator (ADAM-4011D only)

The 4½ digits LED display on the back of the ADAM-4011D lets you monitor the process readings right at their source. The module displays readings in a wide variety of formats as well as high-low alarm messages. The ADAM-4011D offers flexibility, easy installation, and direct availability of process data. For critical process monitoring, this module is the ideal choice.

Digital Input/Output

The ADAM-4011/4011D Thermocouple Input Modules also contain 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 may be used to control 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.
