The Define Instruments Merlin Digital Indicator is a highly versatile panel meter designed without buttons to avoid the risk of accidental parameter alterations during handling. It features configurable decimal point options that can display a scaled version of input signals in order to show a value that is more relevant to your process.

Optional outputs are available; two 3 Amp relays for on/off control and alarm functions, and a loop powered 4 to 20mA active output for retransmission to PLCs and SCADA systems.

The universal wide range AC/DC power supply suits both AC mains and 24VDC applications. It supplies the excitation required by most common sensors and transmitters and can be used to power up to two wire transmitters without an external power supply. It accepts analog inputs from a range of industrial sensors, including: process, temperature, flow, frequency, and voltage.

Program the Merlin in less than a minute using the free download of the ToolBox software and the USB Bridge Key. The unit does not need to power up to be configured as it uses its own excitation voltage. Each range is pre-calibrated so it can be configured without having a sensor present.
