MyDro 850 Remote Terminal Unit
The MyDro 850 is Mission Communications’ most advanced remote terminal unit, purpose-built for master pump stations, critical process monitoring, and complex multi-point control applications. It delivers real-time alarm data and streaming analog values reported every two minutes or on 5% change, providing the continuous visibility that high-priority infrastructure demands.

- Reporting
- Every 2 min or on 5% change
- Onboard I/O
- 8 digital · 2 analog · 3 relay
- Cellular
- Multi-carrier 4G LTE CAT. 1
- Backup
- Up to 18 hours battery
Real-Time Streaming Data
Unlike RTUs that report on fixed intervals, the MyDro 850 streams analog data in near real-time. Analog values are reported every two minutes or whenever a 5% change is detected, whichever comes first.
This streaming approach captures rapid fluctuations in levels, pressures, and flows that interval-based reporting would miss. Pump states are reported in real-time with support for up to eight configurable pump runs and simultaneous runtime tracking for up to seven pumps.

I/O Capabilities
The MyDro 850 delivers extensive input/output capacity out of the box, with expansion options to scale for the most demanding installations:
- 8 onboard digital inputs with selectable wire fault supervision or direct attach current sensing switch; expandable to 16 with PN OP653 expansion module
- 2 onboard analog inputs (4-20 mA isolated or 0-5 VDC) with 4 alarm set points each; expandable to 9 with PN OP465 module
- 3 remotely controllable relay outputs (Form C, dry contact, 5A at 30VDC, SPDT, N/O or N/C); expandable to 9 with PN OP654 module
- 4 pulse input channels with Safe Module Plus expansion module (PN OP750) with 2-minute reporting
- 4 analog output channels (4-20 mA) with PN OP461 module
- RS485 support for specified expansion modules
- Electronic key reader for site activity tracking and service mode

Automated Control Features
The MyDro 850 supports advanced automated control capabilities that eliminate the need for separate PLCs or radio networks:

Digital Interconnect
A digital input/output change at one RTU automatically triggers a relay change at another RTU. Automate site-to-site control without private radio networks.
Analog Interconnect
Mirror analog values between locations in real-time for coordinated process control.
Tank and Well Control
Automatically command well pumps on and off based on tank level readings. Supports up to five outputs (pumps, valves, etc.).
Emergency Backup Pump Control
Software-enabled feature that temporarily takes over pump control for up to two pumps when the primary controller fails.

Frequently Asked Questions
What kind of applications is the Mydro 850 built for?
The Mydro 850 is suited for monitoring applications that need strong performance, reliable communications, and more advanced capability in the field. It is a fit for systems where higher demand or more complex monitoring is involved.
How does the Mydro 850 support remote monitoring?
It supports remote monitoring by collecting site data, sending alerts, and integrating with the Mission’s 123SCADA platform for visibility and control. That helps users manage important assets without needing to stay on site.
Why would a utility choose the Mydro 850 over another RTU?
A utility may choose the Mydro 850 when it needs more capability, stronger performance, or a product designed for more demanding monitoring environments. The choice depends on site requirements and operational goals.
