MD610 High-Precision Process Indicator
The MD610 is a compact, high-accuracy process indicator featuring a dual 4-digit LED display (PV + SV) and true universal input for TC, RTD, and analog signals (0-10V / 4-20mA). It delivers 0.3% measurement accuracy with a fast 250ms sampling rate, and operates reliably from -30°C to 75°C with an IP65 front panel.
Key functions include 4 configurable alarms with flexible AOP relay mapping, digital input filtering, and optional PV/SV retransmission (0-20mA / 4-20mA) or Modbus RS-485 communication. Available in 5 panel sizes, it is an ideal choice for industrial temperature and process monitoring.

0.3% FS accuracy with dual 4-digit 7-segment LED display (PV red + SV yellow) for simultaneous process value and set value monitoring.
True Universal Input
Supports TC (K, S, R, T, E, J, B, N, WRe3-25, WRe5-26), RTD (PT100, Cu50), and analog signals (0-5V, 1-5V, 0-10V, 4-20mA, 0-20mA).
Built-in 24VDC Auxiliary Power
The Code 2 input version provides 24VDC auxiliary power to directly drive two-wire transmitters (pressure, temperature, etc.).
Flexible Alarm Mapping (AOP)
Up to 4 configurable alarms (UPAL, LoAL, ESAL, EIAL) that can be arbitrarily assigned to any relay (AL1, AL2, AU1, AU2) via the AOP parameter.
Optional Retransmission & Communication
PV or SV can be retransmitted as 0-20mA / 4-20mA for PLC or recorder integration. Optional Modbus RS-485 communication (4800/9600/19200 baud).
Rugged & Wide-Temperature Design
IP65 front panel protection, fully sealed housing, and an extremely wide operating range from -30°C to 75°C.
Fast Sampling & Digital Filtering
250ms sampling rate with configurable digital filter (0-40) to smooth noisy signals and ensure stable readings.
