The DRST-CM detachable display adds Modbus RTU RS-485 serial communications to DRST-AC, DRST-DC, DRST-UN, and DRST-UR units. The unit converts a wide array of sensors and analog device signals like uni- and bipolar mA and voltage signals, potentiometer, Lin. R, RTD and TC, to a Modbus communication line signal. All individual unit operating parameters can easily and quickly be configured by using the Modbus communication or by using the front display menu. The easily readable DRST-CM display can be used to read the process signal, simulate the output signal, indicate sensor errors and internal device errors.
Technical characteristics
DRST-CM has full DRSL-DISPLAY functionality for unit programming, process signal monitoring and diagnostics handling. Modbus RTU protocol is supported using a serial RS-485 communication wiring. Multidrop half-duplex connection via shielded RJ45 connector. High safe galvanic isolation of 2.5 kVAC between the serial wiring and the connected DRST-AC, DRST-DC, DRST-UN, and DRST-UR units. Modbus parameters such as address, baud rate, stop bit(s), and parity bit are configured from the DRST-CM display, which also stores parameters.
Mounting / installation / programming
The DRST-CM can be moved from one device to another. The individual DRST-AC, DRST-DC, DRST-UN, and DRST-UR unit configuration of the first device can be saved and downloaded to subsequent devices. Programmed parameters can be protected by a userdefined password. When mounted on devices that are installed upside down, a menu item allows the display on the 4511 to be rotated 180 degrees and the up/down buttons to switch function.
