Product Details:

FOXBORO 2AO-L2C-D is a high precision analog output module designed for DCS control systems, a reliable industrial instrumentation for process automation. This analog output module is a rack-mounted hardware card built to deliver stable analog control signals to field actuators and control valves. It adopts a compact printed circuit board assembly with protective housing, shielding internal electronic components from vibration, dust and electromagnetic interference inside control cabinets. The module supports two independent analog output channels, each channel can generate adjustable analog signal according to control commands sent by the DCS host controller.

This FOXBORO 2AO-L2C-D DCS card converts digital control instructions from the DCS system into standard analog current signals for field control equipment. It can continuously output 4~20mA analog signals to regulate valve opening and adjust process variables such as pressure, temperature, flow and liquid level. Each channel comes with independent channel diagnosis function, which can detect open circuit, short circuit and abnormal signal status. The module supports hot swap operation, users can replace the hardware without shutting down the whole control system, minimizing downtime for production plants.
